We still have 1 more roster spot to fill for an athletic 4. In Danny's defense, there's not much out there(even around the trade deadline except Tyrus Thomas)
Stromile Swift would be perfect for 10-15 minutes per game. He can catch many oops from Rondo(that use to be thrown to KG) and rebound and block shots.
Melvin Ely is another name. Slightly less athletic, but three times more athletic than BBD.
Kenny Thomas might be best. He can rebound in bunches, post up more than Sheed will, and can still dunk over smaller players in the paint..unlike BBD
