first off let me apologize for my offensive comment. had a rough night but its no excuse. that type of trash doesnt belong on these boards and im usually not the one to post it.
i was never a big fan of thabeet so my judgement of him is admittedly biased. again i apologize to anyone offended in particular to fishy.
Good Lord, don't apologize to me. Seriously, I wouldn't take any kind of offense from that.
First, we gotta separate the notion that Boone, Hilton or Hasheem are not succeeding in the NBA because they're not good defensive players. They were all good defensive players at the collegiate level - they're just not particularly good basketball players when considering the NBA level.
Ricky Moore and Jon Linehan were positively evil defensively in college and neither kid really got a sniff in the NBA. Ray Allen was Charmin soft at UConn, but he's a Hall of Famer. There's a lot that goes into that soup - defense is just one ingredient.
Back to Thabeet.
He was an excellent defensive player at UConn. Teams changed what they did because he was in the middle. He wasn't a great offensive player at UConn - he was a very efficient one by the time he was a junior - but he was a terrific defender. Most of his blocks were not weakside, as I think someone suggested above - I think he was actually somewhat slow to recognize those opportunities which was a function of his inexperience - they were on-ball.
DeJuan Blair did give him trouble, but that's not surprising. Shorter, stronger guys who could get into his chest gave him the same issues that a guy like Anthony Glover gave Emeka.
