He's going nowhere with the Knicks. He's exactly what the Bulls need and if they got him they wouldn't have to rebuild completely. They'd be stacked with Rose (if he can stay healthy), Melo, Butler, Taj, Mirotic, Noah, Augustin, Snell, Hinrich, Dunleavy. Plus they have some draft picks. The only two positions they'd need to fill would be one more 2 guard and one more Center off the bench.
That team has it all. They can score, they can play defense, they can rebound. They're legit contenders.
