My current opinion is that Cam Boozer is the most skilled big I have seen at his age, but I don't believe he'll ever be a good defender, which I think is even more important for bigs. This is based off of like 5 games I've seen with 2 of them being all star like games. It's definitely too early to say anything definitive, I'm excited to see how he does at Duke this year.
I think the top 3 guys, (A.J., Cam, Peterson) are all capable of being #1 option type players. A think A.J. has the best all around game of the 3 which is why I rate him the highest.
