DC is clearly a talented player with an ego and a bad attitude. But if there's anything a great coach and a winning organization can, that's turn these kind of lumps of coals into diamonds.
Stephen Jackson, Latrell Sprewell, Andre Blatche, Tony Allen,
Zach Randolph, Rasheed Wallace, and so on
Boston sends Green, Melo, Bradley and Sully to Kings
Sac sends Cousins, Travis Outlaw and Salmons to Celtics
Add in 2 partially protected 1st round picks over the next 3 years.
Rondo, Lee, Pierce, KG, Cousins
Jet, Salmons, Outlaw, Bass, Wilcox
Cousins could absolutely thrive in a Boston system where Rondo gets him the ball in the right spots, and KG can mentor him with his attitude and how to play like a mobile big.
