As we approach the trade deadline on Feb. 21, some teams will be looking to bolster their squads after the first half of the NBA calendar.
Whether it be a playoff contender or a young team trying to get better, there is always some activity as we head into the playoff push.
Here's a look at each team's main weakness(es) before the All-Star break.
*Note: Power rankings compiled before games on 2/10
1. San Antonio Spurs (39-12): Rebounding
The Spurs are ranked 20th in the NBA in rebounds per game as of this writing. In the 119-109 loss to the Detroit Pistons on Friday, they were out-rebounded, 49-33.
Nobody on the Spurs beyond Tim Duncan is averaging more than 5.5 rebounds per game.
2. Oklahoma City Thunder (38-12): Defensive Rebounding
The Thunder rank second in opponents' field-goal percentage and rank 11th in forced turnovers per game, but they rank 23rd in offensive rebounds allowed per contest. It's part of the reason why they rank 15th in points allowed per game.
3. Miami Heat (33-14): Rebounding
Sensing a trend? The Heat rank dead last in rebounds per game, but they've been able to get away with it to an extent because of their defense and because of their ability to take over games offensively.
4. Denver Nuggets (33-18): Free Throws, Three-Point Shooting
It's scary to think how good the Nuggets would be if they were even decent from the free-throw line and from long distance. They rank 29th in free-throw percentage and 27th from downtown.
5. Los Angeles Clippers (36-17): Free-Throw Shooting
The Clippers have shot 70.6 percent from the charity stripe this season, good for 26th in the NBA. Blake Griffin and DeAndre Jordan certainly haven't helped in that area.
6. New York Knicks (32-17): Defense
The Knicks may rank ninth in points allowed per game, but that's a bit misleading. They rank 18th in the league in opponents' field-goal percentage. Their ability to clean up on the defensive glass has been important in that regard.
7. Memphis Grizzlies (31-18): Offense
The Grizzlies not only rank 27th in points per game, they rank 24th in field-goal percentage. That includes having issues from beyond the arc.
8. Indiana Pacers (31-20): Offense
The Pacers may be the best defensive team in the NBA, but you also need offense. The squad ranks 28th in points per game and 27th in field-goal percentage.
9. Chicago Bulls (30-20): Offense
The Bulls rank in the top three in points allowed per game and opponents' field-goal percentage, but they rank in the bottom 10 in points per game and field-goal percentage.
10. Houston Rockets (28-24): Defense
The Rockets are allowing 102.9 points per contest, ranked 28th in the NBA. They have also allowed opponents to shoot 45.7 percent from the field.
11. Golden State Warriors (30-21): Turnovers, Defensive Rebounding
The Warriors are ranked 28th in turnovers per game and they rank in the bottom three in turnover differential.
Golden State also ranks 19th in opponents' offensive rebounds per game.
12. Brooklyn Nets (29-21): Offense
The Nets rank in the bottom 11 in points per game, field-goal percentage, three-point percentage and free-throw percentage.
Deron Williams, Joe Johnson and Gerald Wallace are all shooting 43 percent or worse from the floor.
13. Boston Celtics (26-23): Rebounding
The Celtics rank 29th in rebounds per game and 27th in rebounding differential. They rank in the bottom three in offensive rebounds per contest.
14. Atlanta Hawks (27-22): Rebounding
The Hawks rank in the bottom six in rebounds per game and rebounding differential. They also have a hard time crashing the glass on the offensive end.
15. Los Angeles Lakers (24-27): Defense, Turnovers
Not only have the Lakers allowed opponents to shoot 45 percent from the floor this season, they don't force a lot of turnovers.
On top of that, they turn the ball over a lot themselves and rank in the bottom three in turnover differential.
16. Utah Jazz (28-24): Defense
The Jazz have allowed opponents to shoot 45.9 percent from the field this season, including 37.8 percent from downtown (27th). The 120 points allowed to the Sacramento Kings on Saturday is proof they have issues on defense.
17. Milwaukee Bucks (25-24): Offense
The Bucks rank 12th in points per game, but that's misleading. They force a lot of turnovers and clean up on the offensive glass, which hides the fact that they're shooting 43.3 percent as a team.
18. Portland Trail Blazers (25-25): Defense
The Trail Blazers rank 25th in the NBA in opponents' field-goal percentage. They also don't force a lot of turnovers.
19. Dallas Mavericks (22-28): Rebounding
The Mavericks rank 14th in the NBA in rebounds per game. What's worse, they rank 28th in rebounding differential, allowing opponents to clean up on the glass.
20. Philadelphia 76ers (22-27): Offense
The 76ers are shooting 44.3 percent from the floor as a team, and they rank 29th in points per game this season.
21. Toronto Raptors (18-32): Defense
The addition of Rudy Gay helped Toronto's offense, but the team is still allowing opponents to bomb away. They are allowing opponents to shoot over 46 percent from the field.
22. Detroit Pistons (20-32): Offense
The Pistons rank 19th in points per game and are shooting 44.7 percent from the floor, in the bottom half of the league.
23. Minnesota Timberwolves (18-29): Offense
The Timberwolves are not only ranked 21st in points per contest, they're ranked 25th in field-goal percentage. They also rank in the bottom 10 in turnovers per game.
24. Cleveland Cavaliers (16-35): Defense, Offense
The Cavaliers rank dead last in opponents' field-goal percentage, and they are fouling way too much. Beyond that, they rank 28th in field-goal percentage.
25. New Orleans Hornets (17-33): Defense, Rebounding
The Hornets are allowing opponents to shoot 46.6 percent from the floor, and they rank 22nd in rebounds per contest.
26. Washington Wizards (14-35): Offense
The Wizards are shooting 42.4 percent from the floor this season, 29th in the NBA. On the other hand, the defense has been good.
27. Phoenix Suns (17-34): Defense, Rebounding
You could have expected the Suns to have a tougher time offensively without Steve Nash this season, but the defense has been ugly, too. Opponents are shooting 46.9 percent from the field.
The Suns also rank 25th in rebounds per game and 26th in rebounding differential.
28. Sacramento Kings (18-33): Defense, Rebounding
Newsflash: The Kings can't play defense.
Nothing new. Sacramento is ranked 28th in opponents' field-goal percentage this season and dead last in points allowed per game.
The Kings also rank 29th in rebounding differential.
29. Orlando Magic (14-36): Offense, Defense
Offense is about more than field-goal percentage. You also have to find ways to score. The Magic are shooting over 45 percent from the floor, but they've attempted the fewest free throws per game in the NBA.
Orlando has also allowed opponents to shoot 45.9 percent from the floor while forcing the fewest turnovers per game.
30. Charlotte Bobcats (11-39): Everything
You don't post the worst point differential in the league (-8.8 per game) without doing a lot wrong. The Bobcats can't defend, they can't score, they can't rebound and they don't force a lot of turnovers.
If there's one positive, it's that they rank fourth in turnovers per game.
