Gibson doesn't get enough credit. He's the motor when Noah sits and is a solid player who is scrappy. His offense is nothing to really talk about, but he isn't a liability on offense either. What he lacks in his post game he makes up for it with his tough defense.
I really hope Rose gets that second man soon to help him out. Current roster, like I said, Deng is still that second option and come playoff time they'll have that same problem if Rose does come back. Defenses will concentrate on Rose, knowing that the other Bulls can't really create their own shots. They probably won't sit Rose the whole season, but I think it would be better for their future.
