Presti said he did not enter the trade deadline looking to deal the 6-foot-9, 235-pound Green, a fourth-year player out of Georgetown.
"That was not an objective," Presti explained. "There were only a couple of players I would consider, and Perkins happened to be one of them.
"If we could not have gotten Perkins, we would have been happy standing pat (with Green on the roster), but you can't just get a guy like Kendrick Perkins. You can't just get guys like that. It will cost you something. He's a 26-year-old beast. He's a championship-level, experienced guy, but he's young. He fits our timeline tremendously."
