I don't think this is the worst back court- its decent and Phil Jackson has proved you can win with decent pieces.
Last night, there was a play where Shumpert came around a screen or pick at the top of the key, got open for a decent 15 footer, and took it. Not sure if he missed it or not, but he had an opening in to the lane he could have taken.
But, MDA with his take good, open shots and win on volume encourages these players to take the first open shot, and not necessarily penetrate into the lane.
A different coach and philosophy gets more out of this line up, back court and front court included.
