I was kind of disappointed with Bynum's performance since I had high expectations on how much damage he would do against the Celtics and considering what he did last Christmas vs. the Suns, but overall he did pretty good today.
KG IS somewhat right with what he's saying, because defensively they would play a Center the same as any other Center in the league. But where KG is wrong is that Bynum makes a huge difference on the defensive end compared to last year. Simply his presence on D and him making Pau move to his more comfortable PF position is a huge difference from last year in my opinion.
He's not right at all. Your problem is you're only looking at a stat sheet. Yeah, he blocked only twice, but just being their deters many more shots.
Also, his presence allows Pau to move to PF, where he gets guarded by Garnett who is much smaller, than Perkins. It's a difference story to be guarded by 300 lbs, than by 240 lbs.
