I don't see any reason to cut anyone at this point. The candidates for being cut are all dirt cheap, and Shakur is the only one likely to get no PT. But right now, Greene is playing for a contract, and even with very little offensive game, he's almost looking too good to be true. He could easily be signed, then lose his hunger, because what are we going to do if he lapses into mediocrity? We'd play him anyway, because we wouldn't have any choice.
I didn't expect much of Greene, but it seems that he's not bad at all when he's extremely motivated. I think we need to keep some fire under his butt. I want an inexpensive PG who is dying for PT waiting in the wings, even if we only see him during garbage time. Shakur will do nicely.
