Plenty to prove in Chicago

The top prospects in the 2003 NBA draft won't arrive in town until Saturday, but several players have plenty to gain this week at the Chicago pre-draft camp. Here is a quick glance at 20 players who could make or break their draft status starting Tuesday night.

1. Troy Bell, Sr., PG, Boston College: Bell can score. No one doubts his ability to put the ball in the basket. But he'll have to prove to the NBA brass that he can be a true point guard. Bell played the position some at BC, but not exclusively. If he can prove to be a distributor, he's got an outside shot to sneak into the first round. The more likely scenario is that he'll lock in a top-10 spot in the second round.

2. Marcus Hatten, Sr., PG, St. John's: Hatten is in the same position as Bell. He was a breakout scorer for the Red Storm. He has a chance to shine in three games in Chicago and crack the first round. If he doesn't wow scouts then he'll likely fall in line with or ahead of Bell atop the second round.

3. Ron Slay, Sr., PF, Tennessee: Slay was one of the most prolific scorers in the SEC. He proved the ACL injury he suffered in 2002 shouldn't be a concern after returning without a hitch this past season. But scouts have concerns about his size to play in the post. He'll really have to convince them that he's a forward who can score and defend, regardless of his height. If Slay can dominate a game or two in Chicago, he'll likely increase his workout load with other teams prior to the draft. Slay is a reach for the first round, but a lock for the second.

4. Dahntay Jones, Sr., SG, Duke:Jones could be this year's Freddie Jones. The former Oregon guard impressed NBA scouts with his athleticism so much that he landed among the top top 15 picks (No. 14 to Indiana). This Jones is also a physical specimen, cut and strong, a player who can make shots from all over the court. He can defend and block shots, too. NBA teams will have to get over his lack of a true position. If they can, then Jones has a realistic shot to move into the first round.

5. Kyle Korver, Sr., SF, Creighton: NBA teams flocked to see Korver in Omaha and elsewhere this season to see if he could shoot as well as advertised. He can. But he's more of a catch-and-shoot player. Korver has to prove this week that he can put the ball on the floor to get his own shots, as well as show that he's not slow defensively. He's another player who someone could like late in the first round, but is more likely a second-round pick.

6. Mo Williams, So., PG, Alabama: Williams is still on the fence about whether to return to school. Williams has to show that he's a top 20-25 pick to stay in the draft. To do that Williams, will need to beat out Jameer Nelson, Bell, Hatten and Marcus Moore. If Williams is one of the two best point guards in the camp, he's likely gone. If he doesn't play well during the three days, Alabama coach Mark Gottfried might catch a break and get him back for his junior season.

7. Jameer Nelson, Jr., PG, Saint Joseph's: Nelson hasn't worked out for any teams and is going to Chicago to see if he's first-round material. He's not going to suddenly shoot up over six feet. He is what he is and that's a scoring point guard with a very quick first step. His defense has improved and he's looking more and more like a second-round pick. If someone falls in love with him this week, and sees him as a late first-rounder, then Nelson will consider the jump. But he would almost need such a guarantee to stay in the draft.

8. Tommy Smith, Sr., F, Arizona State: Smith was one of the standouts at the Portsmouth Invitational for seniors. But the key will be whether he was a one-hit wonder. If he stars in Chicago then he's got a legit shot to get in the second round, possibly into the middle of the second. Scouts will be watching to see if Smith has the staying power to hold up over two scouting camps.

9. Luke Walton, Sr., F, Arizona: Walton is far from a lock for the first round. He is one of the best passers in the draft. But the knock on Walton is his size to play inside. He would have to play small forward in the NBA and the question that will dog him in Chicago is whether he can defend an NBA small forward. If Walton shows he can, he's got a shot to go high in the second round. He'll have to really climb, however, to get into the late first round.

10. Hollis Price, Sr., G, Oklahoma: Price will be the toughest player in the camp. He's already proven to be one of the best leaders in college basketball the past two seasons. That's great, but for the NBA, he has to prove he can play the point. He's a scoring guard who excelled in Oklahoma's system. He must prove that he can be more of a distributor for him to get into the upper part of the second round.

11. Keith Bogans, Sr., G, Kentucky: Bogans is back in Chicago after declaring early two years ago as a sophomore and ultimately returning to school. He's an erratic shooter and not seen as a tremendously talented penetrating guard. He'll have to make shots to feel secure about getting drafted in the second round. Bogans could fall prey to senioritis among the NBA teams. If they didn't love him after his sophomore year, then they might be turned off after his senior season.

12 James Lang, Central Park Christian H.S., Birmingham, Ala.: Lang might end up being the only high school senior at the camp. If that's the case then he'll stand out. But he already does. Lang is a wide-body and needs to ensure that his weight doesn't bring down his stock. If he can show that his body is movable then he's got a shot to go high in the second round.

13. Marcus Moore, Jr., G, Washington State: Moore might have declared even if Paul Graham didn't get fired. But the hiring of Dick Bennett meant Moore was gone. Moore's game is uptempo and he didn't want to stick around if he was going to go at a slower pace. But Moore has to prove he can be a true point for the scouts to be enamored with him for a high second-round spot.

14. Ruben Douglas, Sr., G, New Mexico: Scoring was never an issue for Douglas in college. (He led all Division I players in 2002-03 at 28.0 ppg) But the Lobos' go-to scorer will have to stand out in Chicago. His early workouts were positive, but he needs to continue to make a statement. Big-time scorers from lower-profile programs haven't always resonated with the NBA. Douglas could change that mindset if he displays his ballhandling skills well enough in Chicago and beyond this month.

15. Jason Kapono, Sr., G, UCLA: Kapono, like Korver, is one of the best stand-still shooters in this draft. That alone could help him go high in the second round. But Kapono has to do more. He's got to show he isn't a defensive liability. If he can drive to the basket consistently then he's got a chance to improve his stock.

16. Travis Hansen, Sr., G, BYU: Hansen helped himself in Portsmouth. He has shot the ball well throughout May. If he can do the same in Chicago, Hansen has a shot at cracking the top tier of the second round. Scouts will look to see if he can remain a consistent perimeter threat under pressure.

17. Carl English, Jr., G, Hawaii: English is another solid scorer from the wing ... but the question remains: Can he play the point? If he can, English has a chance to move himself up in the draft. If he's strictly a gritty driver to the basket, or a jump shooter, then he won't come near the top of the second round.

18. Marquis Daniels, Sr., G, Auburn: Daniels really helped himself in the NCAA Tournament. His game against Saint Joseph's in the NCAA first round might have locked him into the second round. He has worked out well so far, but if he can play some defense and keep on scoring, then he has a chance to move up after Chicago.

19. Andre Emmett, Jr., F, Texas Tech: Emmett hasn't hired an agent so he could still return to school. Emmett could be the sleeper in this bunch, as well as the Chicago camp. Emmett is a big-time scorer, regardless of position. If he comes close to being a 20-plus point scorer for three days this week then he could easily stay in the draft.

20. Jarvis Hayes, Jr., G, Georgia: Hayes remains on the list to play in Chicago. But the NBA wouldn't be surprised if he passes on the camp. If he doesn't, then he'll probably be the only player in Chicago that has the potential to crack the lottery. If he skips the camp, he's still a late lottery to mid-teens pick in the first round.
