Frazier is a classic case of many UF guards in the Donovan Era. He simply didn't develop. Whether it was lack of work ethic, lack of tutelage, or lack of Donovan's confidence in Frazier, he simply didn't develop. This is the first year that Frazier was asked to create his own shot, so there is really no evidence that he can't create some ability there. There are rumors that Frazier and Donovan didn't get along, and I tend to believe them. Donovan has a history of slow playing freshmen, and that can linger in some players as their careers progress. In Frazier's case, I think they way he has been handled has probably affected his confidence. Not saying that Frazier shouldn't toughen up, just think the personalities probably didn't mesh well...especially this year. I hope that Frazier finishes his degree (if he isn't graduating early). If he doesn't make it in the NBA, there are worse things than making several hundreds of thousands of dollars while living in Europe.
Walker should have been a defensive nightmare. Regardless of offense, he had every ability to be a Ben Wallace type player. Every year he stays his potential turns to lack of ability, much like Young. Good luck to him. His athletic ability will shine somewhere, if he leaves.
I agree that Dodo will get drafted higher than the other two, but I really don't know why he should. He's a big guy with very mediocre guard skills, and no real post game. He just never seems to really love playing the game.
