I don't remember anyone up in arms about the Celts letting Tony Allen go when he signed last year. He was decent last year, but he had zero Offense.
I still disagree about the Perkins trade. He offered them very little on Offense. His rebounding is much better than anything they have no doubt. But again, with no one to cover Lebron, I don't see how Perkins would have helped that. Lebron is still gonna go to the rack if Perk was playing. The problem with the Green move, was that Green was dreadful. Not sure if he couldn't adjust or what. If he played better, no one would mentioned a thing about Perkins.
