One thing that no one should ignore is hunger.
I read this in a blog today, but think about this...
KG, PP, and RA are probably 3 of the most hungriest players in the game. KG showed what he can do when he is around 2 great all stars already.
These guys are gona bond in an instant and put them over the decling Pistons as the best team east easily by just showing up. But when you add in the kind of drive these guys have to finally play on a contending team- watch out.
And don't think for a second Boston will sport that weak bench when the season starts. There are some very good role players that are still are free agents: Miki Moore, Chris Webber, Matt Barnes, Charlie Bell, and Earl Boykins can be attained dirt cheap.
