Pre-draft workouts are a critical part of the NBA draft process. While teams pick their favorites well before the offseason begins, seeing a prospect up close can make all the difference.
Some players have already impressed NBA scouts, coaches and general managers this summer, making strong cases for themselves and moving up NBA draft boards.
Here we'll run through all 30 first-round picks in this summer's draft, highlighting players who are sure to fly up big boards this June.

No. 1, Cleveland Cavaliers: Nerlens Noel, Kentucky, C
While Nerlens Noel's knee injury is very concerning, he looks to be the best of what the 2013 draft class has to offer. An active and athletic 7-foot shot-blocker, Noel's potential is seemingly endless.
No. 2, Orlando Magic: Victor Oladipo, Indiana, SG
It's been rumored that Orlando is looking to make some moves this summer, possibly parting ways with Arron Afflalo. Therefore, Victor Oladipo could be the guy Orlando decides to start over with at shooting guard.
A tough-minded, top-flight defensive player, Victor Oladipo is a no-brainer for a rebuilding franchise like the Charlotte Bobcats. He's a top-five prospect without question, and considering the Bobcats have needs all across the board, he makes tons of sense at No. 4 overall.
Oladipo has been a star thus far his pre-draft workouts. According to ESPN Insider, he wowed the Phoenix Suns earlier this month. Sources via ESPN say he's even moved into the No. 1-overall pick conversation.
If the Cavaliers go a different direction with the top pick, Oladipo could easily end up in Orlando at No. 2.
No. 3, Washington Wizards: Otto Porter, Georgetown, SF
With Washington already boasting a young and talented back court, the Wizards should look to add a dynamic player on the wing. Georgetown's Otto Porter is a tremendous do-it-all small forward who will give Washington full effort on both ends of the floor each and every night.
No. 4, Charlotte Bobcats: Ben McLemore, Kansas, SG
A phenomenal athlete and shooter, McLemore has all the traits you look for in a starting 2-guard. The only question is whether he'll bring the intensity night in and night out.
No. 5, Phoenix Suns: Anthony Bennett, UNLV, PF
The fact that Anthony Bennett is undersized at the power forward position is a legitimate concern for many of the teams picking early in the first round, but the power and athleticism Bennett put on display last season as a freshman at UNLV is quite impressive.
He met with front office staff in Phoenix recently, so don't be surprised if the Suns round out the top five by selecting the Canadian big man.
No. 6, New Orleans Pelicans: Alex Len, Maryland, C
It's difficult to believe that the New Orleans Pelicans see Robin Lopez as their center of the future. He's a solid contributor, but New Orleans will need to upgrade on the interior if it hopes to survive in the Western Conference.
At 7'1", Alex Len has the height and length to make a difference alongside Anthony Davis.
No. 7, Sacramento Kings: Trey Burke, Michigan, PG
Trey Burke can do it all at the point guard position. A gifted scorer with excellent vision, Burke won National Player of the Year honors last season as a sophomore with Michigan.
He averaged 18.6 points and 6.7 assists per game for the Wolverines while leading them to the national championship.
No. 8, Detroit Pistons: Michael Carter-Williams, Syracuse, PG
Detroit Pistons guard Brandon Knight can play just as effectively off the ball, which opens the door for Detroit to draft former Syracuse point guard Michael Carter-Williams at No. 8 overall.
According to ESPN Insider, Carter-Williams has looked strong in pre-draft workouts and is picking up steam thanks to his length and 6'6" frame.
There's no doubt that Carter-Williams will be a lottery pick considering he's one of the top-two floor generals in this year's class. If there's a knock on him, it's his inconsistent jump shot and how it can limit him at the next level.
No. 9, Minnesota Timberwolves: Kentavious Caldwell-Pope, Georgia, SG
A solid shooter with deep range, Kentavious Caldwell-Pope is the sort of wing scorer the Minnesota Timberwolves are looking for in the first round this year. He poured in more than two three three-pointers per game for Georgia last season as a sophomore, hitting 37 percent from beyond the arc.
No. 10, Portland Trail Blazers: C.J. McCollum, Lehigh, PG
Portland is set at point guard with Rookie of the Year Damian Lillard leading the squad, but Lehigh's C.J. McCollum is a versatile combo guard who can play alongside Lillard without taking away his scoring opportunities.
No. 11, Philadelphia 76ers: Jamaal Franklin, San Diego State, SG
With Dario Saric withdrawing from this year's draft and Jamaal Franklin showing a much-improved jump shot, don't be surprised to see the former San Diego State high-flyer breaking through into the lottery this summer.
Although he's been hampered by an ankle injury, Franklin has been able to show off for several NBA teams who love his athleticism and 6'11" wingspan.
Franklin averaged 17 points per game as a junior last season, but struggled to shoot a high percentage, connecting on just 41 percent of his shots from the field and hitting 28 percent of his three-pointers.
According to ESPN Insider, Franklin shot the ball well in a recent workout in Vegas, suggesting he could move up some draft boards.
No. 12, Oklahoma City Thunder (via Toronto Raptors): Cody Zeller, Indiana, C
Oklahoma City would be a good fit for big man Cody Zeller. The 7-footer would give the Thunder an inside presence on both ends of the floor and wouldn't need to make a huge impact right away with Russell Westbrook and Kevin Durant carrying most of the offensive burden.
No. 13, Dallas Mavericks: Steven Adams, Pittsburgh, C
It's quite possible that the Dallas Mavericks deal the No. 13 pick this summer. If they hold onto it, however, they could look to take a strong big in Pittsburgh's Steven Adams.
Adams is a 7-footer with massive hands and an NBA-ready body. He's raw, but his motor and prowess on the glass make him a valuable frontcourt piece.
No. 14, Utah Jazz: Dennis Schroeder, Germany, PG
The Utah Jazz could certainly use some help at point guard, which is why Germany's Dennis Schroeder makes a lot of sense to round out the lottery. A 6'2" guard with a 6'8" wingspan, Schroeder is lethal when he attacks the basket and is incredibly quick in the open court.
No. 15, Milwaukee Bucks: Shane Larkin, Miami, PG
With Monta Ellis reportedly opting out of the final year of his contract with Milwaukee, and Brandon Jennings' future uncertain (restricted free agent), the Bucks could definitely make a run at Miami's Shane Larkin this summer.
Larkin's shooting touch combined with his ability to thrive in the pick-and-roll makes him an appealing pick in the middle of the first round.
No. 16, Boston Celtics: Ricardo Ledo, Providence, SG
Former Providence combo guard Ricardo Ledo has been awfully impressive in pre-draft workouts this summer, according to ESPN Insider. Although he's flying under the radar, he could easily have his name called in the middle of the first round.
The Boston Celtics are a team that's looking to get younger and more athletic, which makes Ledo a no-brainer at No. 16. He can shoot the ball with range or penetrate effectively and get to the rim.
If he doesn't come off the board here, it won't be long before a team snatches him up.
No. 17, Atlanta Hawks: Shabazz Muhammad, UCLA, SF
Shabazz Muhammad will have a lot to prove at the next level. He's not the greatest athlete, and there are concerns that he's a one-dimensional player. Still, Muhammad did enough in his freshman season at UCLA to warrant a mid first-round selection.
He averaged nearly 18 points per game last season on 44 percent shooting from the field and 38 percent shooting from downtown.
No. 18, Atlanta Hawks (via Houston Rockets): Rudy Gobert, France, PF
It's going to be hard for a team like the Hawks to pass on France's Rudy Gobert, especially with back-to-back picks in the middle of the first round. A 7'2" center who can elevate, rebound and run the floor, Gobert is a bit of a project, but one with tremendous upside.
No. 19, Cleveland Cavaliers (via Phoenix Suns from Miami Heat): Sergey Karasev, Russia, SG
A smart, skilled player who isn't limited to just one position on the floor, Russia's Sergey Karasev would be an ideal pickup for the Cavaliers at No. 19. At 6'7" with a 6'9" wingspan, Karasev has excellent size that will allow him to play at the 2 or the 3 spot.
No. 20, Chicago Bulls: Mason Plumlee, Duke, PF
Mason Plumlee is excellent at running the floor and playing big around the rim. The Chicago Bulls could use his energy as well as his athleticism next to Joakim Noah. Plumlee is very explosive for a 7-footer which will have many teams interested in drafting him in this range.
No. 21, Utah Jazz (via Golden State Warriors): Kelly Olynyk, Gonzaga, C
Paul Millsap and Al Jefferson could both become unrestricted free agents this summer, meaning that the Jazz could soon be in need of frontcourt help.
Gonzaga's Kelly Olynyk may not be the tough center most teams are looking for, but he's versatile on the offensive end and plays with great intensity. He makes a lot of sense for Utah at No. 21 assuming he's still on the board.
No. 22, Brooklyn Nets: Jeff Withey, Kansas, C
Jeff Withey is an exceptional player around the rim. Whether he's tipping in misses on the offensive end or swatting shots on defense, the 7-footer is mobile and has excellent anticipation.
No. 23, Indiana Pacers: Reggie Bullock, North Carolina, SF
Indiana already has the system and pieces in place to contend for a championship for years to come. That said, the Pacers could look to add an outside shooter like North Carolina's Reggie Bullock, who shot just under 44 percent from beyond the arc for the Tar Heels last season.
No. 24, New York Knicks: Tony Mitchell, North Texas, SF
Tony Mitchell is the type of player that could help the New York Knicks in at least one key area: rebounding. Mitchell turned 21 in April and is a reliable rebounder for a 6'9" power forward. He averaged 8.5 rebounds per game this past season after reeling in 10.3 per game as a freshman at North Texas.
No. 25, Los Angeles Clippers: Glen Rice, Jr., NBA D-League, SG
Glen Rice Jr.'s experience playing in the NBA Development League last season sets him apart from all of the other first-round prospects, but the fact that he was kicked off Georgia Tech's squad is a major concern for NBA teams.
No. 26, Minnesota Timberwolves (via Memphis Grizzlies): Gorgui Dieng, Louisville, C
Gorgui Dieng is showing lots of improvement on the offensive end where he has developed a nice mid-range shot. But it's his defense that will make him a coveted player late in the first round.
His 7'4" wingspan allows him to disrupt nearly every shot and sets the tone defensively.
No. 27, Denver Nuggets: Isaiah Canaan, Murray State, PG
Murray State's Isaiah Canaan is an exciting, quick scoring guard who would fit in well with the Denver Nuggets and their high-octane offense. He averaged nearly 22 points per game last season for the Racers, pouring in three-pointers at a rate of three per game and averaging over four assists per outing as well.
No. 28, San Antonio Spurs: Lucas Nogueira, Brazil, C
The San Antonio Spurs have a history of developing international talent, and Brazil's Lucas Nogueira could be next. An aggressive, high-energy center, Nogueira is an outstanding shot-blocker and is also impressive on the boards, where his 7-foot frame and 7'6" wingspan give him an edge.
No. 29, Oklahoma City Thunder: Tim Hardaway Jr., Michigan, SG
An athletic shooting guard who can create for himself off the dribble or with a jump shot, Tim Hardaway Jr. looks to be a solid first-round pick. He isn't always as involved as he should be, but he's an excellent all-round talent who will likely interest the Thunder at No. 29 overall.
No. 30, Phoenix Suns (via Cleveland Cavaliers from L.A. Lakers): Allen Crabbe, Cal, SG
The Phoenix Suns could really use Allen Crabbe's scoring punch on the wing. He averaged 18.4 points per game last season for Cal, shooting 46 percent from the field and 35 percent from beyond the arc.
Crabbe is also a strong rebounder for a 2-guard, averaging six per game for the Golden Bears last year.
