And I would add that Austin Rivers is a TERRIBLE finisher and decision maker in the lane and maybe one of the worst defensive guards I have ever seen. He will foul out of NBA games in under 10 minutes. His primary defensive manuever is to take two hands and grab the ball handler who tries to go by him. After his 3rd foul, that startegy turns into, "Simply let the guy blow by you." It is hard to believe that he is Doc Rivers' son.
On the plus side - he has good shooting range and I think the NBA 3 will not be a struggle for him. I think you have to view him as basically an unathletic white shooting guard - good standstill shooter who gives you absolutely nothing else. Steve Kerr, Tim Legler, that type of player. I would say J.J. Redick, but Redick is a FAR better player and actually tries to improve himself every year.
I am torn on Harrison Barnes because he was not a center and yet he was the #1 overall high school prospect. That generally DOES translate over into decent pro success.
Barnes, given a good team, will be able to make open shots, be adequate on defense, and rebound OK. If, however, someone expects him to carry a team and make contested shots, that isn't going to happen.
So - maybe a worse version of Jamal Mashburn.
