Report Card Grades for All 30 NBA Coaches at the All-Star Break

Thanks to the lockout, players, teams and coaches did not get much time to prepare for this fast-paced season. 

Without a full training camp and preseason, the NBA was thrown into action long before many teams were ready. 

As we approach the All-Star break, it's time to take a look at how each coach has done with the challenges they have faced.

Here are the grades for NBA head coaches so far this season. 

Larry Drew, Atlanta Hawks

Offensive Rating: 102.8 (16th of 30)

Defensive Rating: 100.4 (9th of 30)

Overall Record: 19-13, Sixth in Eastern Conference

Larry Drew has led the Atlanta Hawks to a familiar position this season, as they are once again a middle-of-the-pack team in the Eastern Conference playoff picture. 

At this point in the season, his team's record is ahead of the winning percentage that the team finished with last season. 

Drew does get credit for managing his team despite injuries to some of his best players. 

The real grade for Drew will come after the playoffs depending on how deep the Hawks make it. 

Grade: B

Doc Rivers, Boston Celtics

Offensive Rating: 100.0 (24th of 30)

Defensive Rating: 98.4 (4th of 30)

Overall Record: 15-16, Eighth in Eastern Conference

Doc Rivers has been one of the better coaches in the NBA during his time in Boston. 

This season, he's dealt with injuries to his top players almost every night.

The Celtics have had their ups and downs this season, and are currently mired in a losing streak. 

Rivers is going to have to work hard during the second half of the season to get his team to hold on to the final playoff spot in the East. 

If they can get to the playoffs and have their full team available, the Boston Celtics will be a team that no one will want to meet in the early rounds.  

Grade: B

Paul Silas, Charlotte Bobcats

Offensive Rating: 94.0 (30th of 30)

Defensive Rating: 109.6 (29th of 30)

Overall Record: 4-27, 15th in Eastern Conference

Another season of disappointment in Charlotte. 

All of the team's problems cannot be blamed on the head coach, but Paul Silas may be on the move after only two seasons with the Bobcats. 

He has not been given much talent to work with, but the team should have more than four wins so far this season. They are on pace to end the season with about 10 total wins. 

The only bright spot has been the play of rookie Kemba Walker, who will be the team's point guard until his rookie contract expires. 

Grade: F

Tom Thibodeau, Chicago Bulls

Offensive Rating: 107.8 (3rd of 30)

Defensive Rating: 97.6 (2nd of 30)

Overall Record: 26-8, Second in Eastern Conference

Tom Thibodeau has enjoyed the benefit of having a strong team led by reigning league MVP Derrick Rose. 

The Bulls are playing well again this season and are in contention for ending with the best record in the NBA. 

They have faced some adversity as Rose missed several games with injuries, but the rest of the team picked it up the slack.

The Bulls are still on track to challenge for the Eastern Conference Championship and possibly make it to the NBA Finals.

Grade: A

Byron Scott, Cleveland Cavaliers

Offensive Rating: 101.4 (22nd of 30)

Defensive Rating: 105.4 (23rd of 30)

Overall Record: 12-17, Ninth in Eastern Conference

Byron Scott has done a pretty good job overall in Cleveland this season and has the Cavaliers just outside the Eastern Conference playoff picture in ninth place.

It has helped that the team has found a solid point guard in rookie Kyrie Irving. 

Scott will have his work cut out for him while Anderson Varejao is out with a wrist injury. If the team can stay in the playoff hunt until he gets back, they may just make a run and sneak into the eighth spot in the East. 

Grade: B+

Rick Carlisle, Dallas Mavericks

Offensive Rating: 102.0 (21st of 30)

Defensive Rating: 97.9 (3rd of 30) 

Overall Record: 21-12, Third in Western Conference

After a rough start where the Dallas Mavericks looked like anything but the defending World Champions, Rick Carlisle has turned things around for his team. 

The Mavericks now sit in third place in the West behind only the Oklahoma City Thunder and the San Antonio Spurs. 

It took them a little while this season, but the team has adjusted to losing center Tyson Chandler to free agency and is back to being one of the top defensive teams in the league. 

Grade: A

George Karl, Denver Nuggets

Offensive Rating: 106.9 (6th of 30)

Defensive Rating: 103.8 (17th of 30)

Overall Record: 18-15, Eighth in Western Conference

The Denver Nuggets jumped out to a hot start but have since cooled off with injuries taking a toll on this team.

Early in the season they were ranked higher, but they have slipped since Danilo Gallinari went down with an ankle injury.

The Nuggets have shown this season that they have not missed Carmelo Anthony, as they are still one of the top offensive teams in the league.

When healthy, the Nuggets will be a team who can surprise others in the playoffs.

George Karl just needs to get them there.  

Grade: B+

Lawrence Frank, Detroit Pistons

Offensive Rating: 99.8 (25th of 30)

Defensive Rating: 107.3 (26th of 30)

Overall Record: 11-23, 11th in Eastern Conference

Lawrence Frank has not done much in his first season in Detroit and the team has already had to turn its focus towards developing young players for the future.

It has been another frustrating season for the Pistons and it seems like it will continue for a long time. 

Throughout his career as an NBA head coach, Frank has had the misfortune of leading bad teams. He has only ended a season above .500 twice in eight years and was 0-16 last year with the New Jersey Nets. 

Unfortunately, it looks like this season is more of the same for Frank.

Grade: D

Mark Jackson, Golden State Warriors

Offensive Rating:  106.2 (7th of 30)

Defensive Rating: 107.9 (27th of 30)

Overall Record: 12-17, 13th in Western Conference

Mark Jackson inherited a team that has little problem scoring, but plays very little defense. 

This is not entirely his fault, as he does not have the right players to carry out the defensive plan that he has been trying to install with the Golden State Warriors. 

Jackson is gaining the reputation of being a player's coach due to spending so long in the league and having played against some of the aging stars who are still playing. 

If Jackson can get the right players in the system he will be successful. 

A true grade for Jackson will have to come after a couple of seasons, but so far he is doing the best he can with what he has.

Grade: C

Kevin McHale, Houston Rockets

Offensive Rating: 105.2 (9th of 30)

Defensive Rating: 103.6 (16th of 30)

Overall Record: 19-14, Sixth in Western Conference

Former Boston Celtics legend Kevin McHale is doing a good job in his first season as the head coach of the Houston Rockets. 

After enduring a very difficult opening schedule, the Rockets won 10 of their next 12 and have been winning since that streak.

McHale and the Rockets have been impressive at times this season and are playing at a high level despite not having a superstar of the team. 

The combination of Kevin Martin, Kyle Lowry and Luis Scola has helped this team to be successful and currently in playoff position.

The Rockets are setting themselves up to be a sleeper team in the postseason.

Kevin McHale should get votes as the Coach of the Year. 

Grade: A

Frank Vogel, Indiana Pacers

Offensive Rating: 102.7 (17th of 30)

Defensive Rating: 100.1 (8th of 30)

Overall Record: 19-12, Fifth in Eastern Conference

Frank Vogel has taken an improved Indiana Pacers team this season to one of the more surprising starts this year. 

Vogel has a good group of young talent and is doing a solid job of developing them. 

This season, the Pacers are far ahead of the pace that they finished at last year and will a team that will be hard to match up with in the playoffs. If they can get up to the fourth spot and earn home-court advantage, they could make it out of the first round for the first time since 2006.

Grade: A

Vinny Del Negro, Los Angeles Clippers

Offensive Rating: 107.7 (4th of 30)

Defensive Rating: 105.0 (22nd of 30)

Overall Record: 19-11, Fourth in Western Conference

With the players that he has in Lob City, Vinny Del Negro has not had to do much to lead this Clippers team. 

With five players averaging double figures, it is easy to see why the team has a top-five offensive rating.

If they could find a way to improve the defense instead of relying on outscoring opponents, they will be a very dangerous team.

Del Negro does have work to do on the defensive end, but any coach who can get the Clippers back into the playoff race deserves a lot of credit.  

Grade: B+

Mike Brown, Los Angeles Lakers

Offensive Rating: 103.1 (14th of 30)

Defensive Rating: 100.6 (10th of 30)

Overall Record: 19-13, Fifth in Western Conference

The Los Angeles Lakers struggled early in this season, but things have since evened out for them. 

Mike Brown has had the difficult task of following Phil Jackson as the coach of the Lakers and has had his growing pains on Kobe Bryant's team. 

Brown needs to find a way to get the bench players to contribute more, as there is a big drop in production after Kobe Bryant, Pau Gasol and Andrew Bynum. 

The Lakers are in fifth place in the Western Conference and need to add a point guard if they are going to make a run in the playoffs. 

Grade: B-

Lionel Hollins, Memphis Grizzlies

Offensive Rating: 102.0 (20th of 30)

Defensive Rating: 101.0 (11th of 30)

Overall Record: 18-15, Seventh in Western Conference

Lionel Hollins is a good coach on a sometimes forgotten team. 

Following a good playoff run last season, the Memphis Grizzlies entered this year with high expectation for success. Those expectations took a turn with the injury to Zach Randolph, but Hollins has still done a good job with his young team. 

Hollins has been able to work well with his players and keep them in the playoff picture until Randolph can return. 

Once he does, the team is once again poised to make some noise in the postseason.

Grade: B+

Erik Spoelstra, Miami Heat

Offensive Rating: 109.4 (1st of 30)

Defensive Rating: 99.7 (7th of 30)

Overall Record: 25-7, First in Eastern Conference

With the team that Erik Spoelstra has, it is almost unfair to give him a grade.

The Miami Heat have a first place offensive rating, but are getting it done on the defensive end as well. 

LeBron James is having the best season of his career, and the team has played better this year overall. 

Spoelstra has had to manage time without Dwyane Wade, who has missed time with injuries, but has had the benefit of James and Chris Bosh to fall back on. 

The Heat continue to be one of the favorites to win the NBA Championship this season. 

Grade: A

Scott Skiles, Milwaukee Bucks

Offensive Rating: 102.7 (18th of 30)

Defensive Rating: 104.5 (19th of 30) 

Overall Record: 13-19, 10th in Eastern Conference

With the amount of injuries that the Milwaukee Bucks have endured this season, being in 10th place in the Eastern Conference is not a bad thing. 

Although they do miss Andrew Bogut, who is out with another injury, point guard Brandon Jennings is playing well this season. 

Scott Skiles' team is less than three games out of a playoff spot but must turn things around after the All-Star break. 

Maybe trading away Stephen Jackson at the trade deadline would be the lift that this team needs to do better going forward. 

Grade: B-

Rick Adelman, Minnesota Timberwolves

Offensive Rating: 102.8 (15th of 30)

Defensive Rating: 101.6 (13th of 30)

Overall Record: 16-17, 10th in Western Conference

The Minnesota Timberwolves are a better team this season, but it does not fully show up in their record. 

Rick Adelman is doing well to manage the different talent levels on this team. He has a good young core of players with Kevin Love, Ricky Rubio and Derrick Williams. 

Six players are averaging double figures and the team is much more exciting to watch. 

At one point this season, Adelman coached his team to an above-.500 record for the first time since 2008. 

Adelman has been a good addition and is doing the right things to turn this team around, it is just going to take some time. 

Grade: B+

Avery Johnson, New Jersey Nets

Offensive Rating: 103.9 (12th of 30)

Defensive Rating: 111.2 (30th of 30)

Overall Record: 10-24, 12th in Eastern Conference

Avery Johnson has the difficult task this season of leading a young team who is not winning many games. 

Distractions surrounding whether or not the team will acquire Dwight Howard have something to do with this, and it is partly due to having young players who are still learning the game. 

Johnson has All-Star talent in Deron Williams, who is doing what he can to help the team, but wins have been difficult to come by. 

Things can turn around dramatically for the Nets if they add Howard at the trade deadline, but the team will have to look to next season for success. 

Grade: C-

Monty Williams, New Orleans Hornets

Offensive Rating: 98.6 (27th of 30)

Defensive Rating: 104.6 (20th of 30)

Overall Record: 7-24, 15th in Western Conference

The New Orleans Hornets were destined to be bad when Chris Paul was traded to the Los Angeles Clippers. 

Heading into this season, Monty Williams did not have an easy task of leading this team. Things got worse when Eric Gordon went down with an injury.

The Hornets have been playing better lately as they had a three-game winning streak, but the season is already lost for the team and they are looking toward the draft. 

Grade: F

Mike D'Antoni, New York Knicks

Offensive Rating: 100.9 (23rd of 30)

Defensive Rating: 99.7 (6th of 30)

Overall Record: 16-17, Seventh in Eastern Conference

Mike D'Antoni of the New York Knicks can thank Jeremy Lin for any grade higher than complete failure this season, and possibly for keeping his job. 

Before "Linsanity" hit the Knicks, they were struggling to play together, share the ball and put together consistent wins. 

With the level of talent on this Knicks team, it should not have taken Jeremy Lin to save the season and get the Knicks into a playoff position. 

Other than taking a gamble on Lin, D'Antoni has not done much with this underperforming team and will likely not be back next season as the head coach. 

Grade: C-

Scott Brooks, Oklahoma City Thunder

Offensive Rating: 108.6 (2nd of 30) 

Defensive Rating: 102.3 (15th of 30)

Overall Record: 25-7, First in Western Conference

Like Erik Spoelstra in Miami, Scott Brooks has the benefit of having great players on his team who do the work each night. 

Brooks is a good coach and has done a good job of helping his team to manage the pressure of being the top team in the Western Conference. 

It helps that he has Kevin Durant, Russell Westbrook and James Harden, but Brooks is doing well to get production from his role players as well. 

At this point of the season, the Oklahoma City Thunder are the team to beat in the Western Conference. 

Grade: A

Stan Van Gundy, Orlando Magic

Offensive Rating: 103.3 (13th of 30)

Defensive Rating: 101.1 (12th of 30) 

Overall Record: 21-12, Third in Eastern Conference

The biggest challenge for Stan Van Gundy and the Orlando Magic this season is trying to stay focused as a team despite all of the rumors surrounding All-Star center Dwight Howard. 

The team is playing well and is behind only the Miami Heat and Chicago Bulls in the Eastern Conference. 

The emergence of Ryan Anderson has been a great help to Howard. Van Gundy has done well to keep this team on track. 

If the team is able to keep Howard past the NBA trade deadline, they will be a strong team in the playoffs. If they are not able to keep him, they will have to look ahead to next season. 

Grade: A

Doug Collins, Philadelphia 76ers

Offensive Rating: 105.2 (8th of 30)

Defensive Rating: 96.9 (1st of 30)

Overall Record: 20-12, Fourth in Eastern Conference

Doug Collins has done a remarkable job with the Philadelphia 76ers this season and is the favorite to win the Coach of the Year Award at the end of the year.

Now coaching his fourth NBA team, Collins has taken a 76ers team that does not have a true superstar and turned them into a contender in a tough Eastern Conference.

Collins has done well to find the right mix of players and get the most out of his young guys on a nightly basis.

The team has shown great improvement since last season, as they are playing with the top defensive rating in the league.  

Grade: A

Alvin Gentry, Phoenix Suns

Offensive Rating: 102.1 (19th of 30)

Defensive Rating: 104.7 (21st of 30)

Overall Record: 14-19, 12th in Western Conference

Alvin Gentry and the Phoenix Suns are having a rough season this year. 

Outside of the ageless Steve Nash and Marcin Gortat, the Suns are not getting the player production that they hoped for and need. 

Gentry is having a hard time getting much out of his players and averages are down for many of them. 

As good as Nash and Gortat have been, they can not carry the team alone. 

Unless they can turn things around soon, Gentry will be looking for a new job at the end of the year following his second losing season in a row. 

Grade: C-

Nate McMillan, Portland Trail Blazers

Offensive Rating:  105.4 (8th of 30)

Defensive Rating: 99.6 (5th of 30) 

Overall Record: 18-16, Ninth in Western Conference

The Portland Trail Blazers are one of the most dangerous teams in the Western Conference, but their record does not show how good they are. 

After jumping out to a fast start, things have cooled off for the team and they now sit just outside the playoff picture. 

The Trail Blazers rank in the top 10 in both offensive and defensive categories, but it has not translated directly into wins. 

McMillan needs to find a way to get his team to win the close games, or this is going to be a long second half of the season for the Blazers. 

All they really need to do is make it into the playoffs, where they are capable of beating any team in the West if they are playing as well as they can. 

Grade: B

Keith Smart, Sacramento Kings

Offensive Rating: 99.3 (26th of 30)

Defensive Rating:  108.2 (28th of 30)

Overall Record: 10-21, 14th in Western Conference

Keith Smart was thrown into the head coaching mix after Paul Westphal was fired after only seven games this season. 

From that point, Smart has not done much better in teaching this young Sacramento Kings team to share the ball and play team basketball. 

This team desperately needs some veteran players to balance out the young guys, who seem to be more interested in scoring themselves than playing together. 

Unless the team makes some changes at the trade deadline or in the offseason, it will not be long until Smart is gone as well. 

Grade: D

Gregg Popovich, San Antonio Spurs

Offensive Rating: 106.8 (6th of 30)

Defensive Rating: 103.2 (15th of 30)

Overall Record: 23-9, Second in Western Conference

Gregg Popovich is one of the best coaches in NBA history and this season he is showing why. 

After losing a key player in Manu Ginobili to an injury and watching a decline in production from the aging Tim Duncan, Popovich has led his team to the second place spot in the Western Conference standings. 

The play of Tony Parker has helped this team to continually find a way to win.

Grade: A

Dwane Casey, Toronto Raptors

Offensive Rating: 97.9 (28th of 30) 

Defensive Rating: 104.0 (18th of 30)

Overall Record: 9-23, 13th in Eastern Conference

Things went from bad to worse for Dwane Casey and the Toronto Raptors when they lost Andrea Bargnani to a calf injury. 

In the 13 games he played, Bargnani was putting up good numbers and was leading the team in scoring. 

The rest of the Raptors have looked lost since he went out and the other guys on the team have not stepped up on a consistent basis. 

Casey has wanted to install a better defensive attitude with the team, but has had to settle for piecing together whatever they can this season. 

Grade: D-

Tyrone Corbin, Utah Jazz

Offensive Rating: 104.5 (10th of 30)

Defensive Rating: 106.1 (24th of 30)

Overall Record: 15-16, 11th in Western Conference

The Utah Jazz started out the season exceeding expectations but have since fallen back to where many predicted them to be. 

Tyrone Corbin has a mix of young players and veterans and must decide who gets the playing time. 

If he plays the veterans, he has a better chance of winning, but if he plays the young guys who have a lot of potential, he gives them the chance to develop faster. 

Before going 3-7 over their last 10 games, the Jazz were playing well and had a winning record. 

If Corbin can find a rotation that works to serve both his veterans and young guys, this team may just sneak into the playoffs.

Picking up a point guard at the trade deadline would help them out as well. 

Grade: B-

Randy Wittman, Washington Wizards

Offensive Rating: 97.5 (29th of 30)

Defensive Rating: 107.1 (25th of 30)

Overall Record: 7-25, 14th in Eastern Conference

Randy Wittman has won more games this season than his predecessor Flip Saunders, but that is not saying much.

Saunders was fired after winning only two games in 17 tries this season. Wittman has added five more wins.

The Wizards have good young talent but can't seem to put together any long-term consistency. 

They are already looking forward to the NBA draft, where they will add another good young player. 

Now they need a coach who can get them all on the same page and get the most out of their talents. 

Grade: F
