Thought of another name.
Thad Young at 6'10"?
That's a keeper.
Like the list mgent gave outside of Randolph and Ibaka.
Randolph I think is already a superstar, Ibaka even at 7'0" I think will still be the same.
If Iguodala isn't a "superstar," then I wouldn't say Randolph is. And Ibaka is one of the best shot blockers the league has seen in a while at 23, I wouldn't underestimate what he could do with 2 more inches. He also has an excellent leaping ability, at 7 foot he could be a very dangerous dunker and rebounder.
Milsap, Lawson, and Collison were all guys I thought of, the latter two especially I don't think have "it" yet. They rely almost purely on speed and shooting to score their points, and don't do a lot other than that. Plus with two inches they'd still be undersized anyway. I think people are putting a little too much stock into height. If you're talking 7'6" that's one thing, but most of the time it's the player not the body. Ben Wallace wasn't outblocking guys twice his size out of luck. Same with Rodman and rebounding.
