Kwame is a good defender and competent rebounder, good health, and can run the floor.
He has no chance of catching any of Rondo's passes, and I think Rondo and KG will get together and beat the crap out of him. So...no on Kwame.
Pryzbilla injured himself in the shower, so...no. We need someone with a good track record of health, IMO.
I'm not sure McRoberts is a viable C for size reasons, but he is a hustle guy, relatively healthy (I think), and that's pretty much what we need. Especially with other guys aging, someone to chase down the ball and give energy would be good. Unfortunately, that's supposed to be BBD's job, if he still wants it.
A team can handle an aging vet, maybe two, with a history of health problems, but last season PROVED that gambling on the health of multiple key players is not a good idea when those key players have show, season after season, that their health just doesn't hold up.
I think it's time for Danny to quit screwing around and lock up a key role player for more than 1-2 seasons.
It's time to sign a guy like Dalembert.
