I like Bane, in the lil bits I've seen him. I'd rather have him than Semi and two future 2nd round picks. But then again..... I'd rather eat glass than watch Semi play basketball. However, assuming he can walk and chew gum at the same time (still very much in question), I'd rather any minutes that would have gone to Bane go to Nesmith.
That said, I agree with Roy -- I think Ainge would have picked Tillman if he'd kept the pick (and wished he would've). Again, I'd rather have him than Semi and two future 2nds.
