According to the Globe's Gary Dzen, Kendrick Perkins looks pretty good during warmups:
Perkins is in uniform and warming up on the parquet. Perkins is taking jump shots over the reach of assistant coach Clifford Ray. He's a righthanded shooter, but his left arm is getting good extension on the jump shots as well. He also blew past Ray for a couple of powerful dunks. He said he could barely lift the arm a couple of days ago in Los Angeles.
