I think Rivers is going to be a bust, honestly. Or maybe not a bust, but at least not a superstar. I see the upper limit of his potential being Monta Ellis - decent volume scorer and not much else.
I would have to say Bradley Beal will be the best guard of this draft. That kid is going to tear things up in the NBA, I think. Lillard I also see big things for.
Waiters and Lamb will be decent, but I don't see either being a superstar to be honest. Potentially All-Stars, though.
