Oh, for Denver, I LOVE the deal. As long as JR can pull in the reins and play under control, he should do well. Have heard alot of people, both fan and "expert" say this is a great trade for JR, but just remember, that he's been under a TIGHT leash by both George Karl and Byron Scott. First sign of mistakes and he gets yanked out with the quickness.
I think the trade will benefit the Denver front line the most. Nene, Kenyon Martin and maybe even Kleiza will see an increase in production with Billups doing the distributing (if he ever shows up)
