Nowhere yet have I seen the most obvious proposal. If we take on Hinrich, Beno has to go:
Beno and Noce for Hinrich and Thomas.
With Hinrich, although expensive and not that young anymore, you hope you have the ideal 6th man PG/SG that can play next to Reke and Martin. Thomas, though, is the whole point of the experiment.
For the Bulls, I guess it's the whole "flexible pieces" argument. Who knows where Amick got this idea from, or if he's just speculating on his own. My guess is the latter.
