Danny's given Doc some players to overhaul his system, but Doc isn't buying it. Sullinger will get you 1-2 more possessions a game as an offensive rebounder, but Doc's system has everybody sprinting back to get set up on defense, so what's the point (loved watching the other guys turn around and stand at half court after Sullinger snatched a missed shot from three Sixers during the second half and got hung out to dry). Darko gives you some options as a passer in the high post - he's riding the bench. Green, Lee, Barbosa can run like the wind and force Rondo (who's nowhere near his ceiling even still) to fall out of love with rock-pounding - they're spare parts out there, glorified fourth options most of the time.
Sit Rondo a few more minutes a game. Put Pierce on the KG 5-5-5 plan. See what you've got with these new guys in November and December. But that won't happen - talent's gotta fit the system with Doc, not the other way around.
