Last years consensus #2 pick, and possible #1 pick leading up to the draft was Evan Turner. He looks at least currently to be a total bust. Funny thing with this draft is that every player could be a bust for where they are taken. Chris Singleton with his length and athleticism could end up being the best SF in this draft, but then again so could DWilliams. It is such a crap shoot.
The one thing I will give DWilliams is that he believes his hype and is a total personality. Guys like that usually have a drive to be great, so I believe he will will himself to greatness or at least very goodness.
I think in 4-5 years any one of the top 4 or 5 players could be the top player coming out of this draft.
