Why didn't the celtics try this trade instead !?!?

wow, thats actually pretty clever, are all their contracts expiring, cuz one of the main reasons why perkins was actually traded was because his contract was going to expire anyways, and he wanted a lot of money for an extention or somethin like that, so instead of giving perkins out for free, they took the deal of gettin jeff green instead, who the boston celtics liked a long time ago, when he was coming right into the NBA
