Ok I saw every game Roy played for the past three years and I think I have a pretty good idea about what he does well and what he does not. There are a lot of misconceptions out there.
1. Evaluate Roy based on his statistics at your own peril. Georgetown over the past several seasons has played at one of the slowest paces in the NCAA. They do not score a lot of points and their system leads to exceptionally balanced scoring. That Roy scored only 13 a game is partly because of his own strengths and weakness, but it is also a product of the Hoyas' offense.
2. Roy is not a great rebounder, but he is not as bad as many think. Six rebounds is admittedly not what you want from a guy that is 7-foot-2. But, again, there were fewer misses in Georgetown games. And, based on watching him play, he grabbed a lot of boards last season that did seem to genuinely require some skill. He can board in traffic.
3. Roy has great low post moves -- probably better than any of these up-and-comers he is being compared to. He has refined his hook shot to the point he can go strong with his left or his right hand and score pretty easily. His footwork is flawless and he also a nice move where he sort of turns and ducks his shoulder and goes around the defender to score. Yes, he may be slow, but his low post moves are his strength.
4. As such, Roy plays well against guys around his size. From the last two years:
1/6/07 vs. Harangody: 18 pts (8-9), 6 reb., 2 blocks
1/13/07 vs. Gray: 11 pts (5-6), 2 reb., 1 block
2/7/07 vs. Padgett: 20 pts (9-10), 11 reb., 1 block
2/10/07 vs. Osmane Baro: 23 pts (7-12), 11 reb., 3 blocks
2/24/07 vs. Gray: 12 pts (4-7), 5 reb., 4 blocks
3/3/07 vs. Thabeet: 18 pts (7-13), 12 reb., 3 blocks
3/9/07 vs. Harangody: 6 pts (3-4), 4 reb.
3/10/07 vs. Gray: 18 pts (8-10), 11 reb., 1 block
3/31/07 vs. Oden: 19 pts (9-13), 6 reb., 1 block
1/12/08 vs. Thabeet: 20 pts (7-14), 8 reb., 1 block
1/19/08 vs. Harangody: 21 pts (7-11), 3 reb., 1 block
1/21/08 vs. Onuaku: 15 pts (5-10), 9 reb.
2/9/08 vs. Padgett: 14 pts (7-9), 4 reb., 2 blocks
2/16/08 vs. Onuaku: 11 pts (4-6), 3 reb.
3/1/08 vs. Baro: 20 pts (7-11), 6 reb.
3/8/08 vs. Padgett: 12 pts (6-12), 6 reb.
So there are a few stinkers in there, but for the most part, he has been very good against guys who are his size. Several of those guys will be players at the next level.
5. Roy struggles against little guys who pester him from below. He just does. He hasn't figured how to solve that. It is a weakness, but one that I don't think he'll have to deal with as much in the NBA. You can't have three 6-foot-4 guys swarm him in the pros.
6. Roy can shoot. Those threes you saw him hit this year were not lucky. He didn't shoot a lot for Georgetown, but he has shown in games and in practice that he is very capable of stepping out and hitting a jumper. He is going to need to do it more in the NBA, but he can do it.
7. Roy will absolutely need to cut down on the cheap fouls. He commits too many of them and it is maddening. It is a great way to take himself out of a game. He needs to be mindful of that.
8. Roy is not lightning fast getting up and down the court, but he is not out of shape. He is slow, I think we all can agree on that, but he runs a lot -- he can be seen jogging up the famous Exorcist steps in Georgetown and running with Mike Sweetney (insert punch line here) through the streets near campus. Unlike Sweetney, Roy is in shape, he just isn't that fast. I can't imagine stamina will be too huge an issue in the NBA.
9. Roy needs to hit the weight room. He has to get stronger.
10. Roy is a very strong character guy. He is extremely well spoken, he is polite, and he has a great sense of humor. He often jokes about running for governor of Maryland when he retires from basketball. He joked earlier this year about growing a Josh Childress-style 'fro. Now, to be sure, drafting on sense of humor would be pretty stupid, but my point is that Roy is good for the locker room and a good representative of a franchise.
