Hibbert is a great example. You may be right about seeing him in person. But he wasn't always the best big man on the floor this season. At times Hibbert and Horford, to give two examples, outplayed him. Yes, they'll both be lottery picks, but not the NBA's best.

If he were in the lineup right now and I had to win a series, I would take several NBA centers over him:
Dwight Howard
Shaq
Bosh
Sheed
Duncan
Stoudamire
Jermaine O'Neal
Boozer
Camby - maybe
Yao - maybe

Many of those guys play PF as well, but have all played Center at one time or another this season and could all match up with Oden in 7 months. He'll certainly make an impact and win plenty of battles, but he's not going to be dominant as a rookie. For starters, unless Stern anoints him under the Dwayne Wade foul rules, he'll have to figure out how to stay in games. Next, he'll have to go through the daily grind of games when a soft opponent is Pao Gasol, not Courtney Sims. When he does that in a few years, he'll be one of the best.
