I loved WW while he was here at OU, and I have absolutely nothing against the guy, but I don't really see him making a big impact in the NBA. He's not a PG, not as tall as advertised, and he shoots from the shoulders which just won't work in the league as a SG (too easy to block/defend with as long as most of the SG's are). I'm not saying he won't make an NBA roster, because I believe he will get a chance, but I don't see him having much relevance there.
We'll see. I could be proven wrong, but if Hollis Price couldn't make an NBA roster (although much shorter, but with a quicker and higher release), I don't see Willie making it long term. He's more athletic than Hollis was, but pretty much everyone in the NBA is just as athletic as he is at his postion. I hope he does well though (it would be good for OU if he can hang around). Only time will tell and I honestly wish him the best. There is money to be made in Europe regardless.
