That's great news! He doesn't even have to be excellent. He just needs to be able to put a body on Gasol to wear out the Laker big man.
During Game 5, Gasol figured out that once he's in the paint, he could score on KG, PJ, and Powe as long as they play him one on one. I suspect he'll have to work really hard just to get to the paint with Perkins playing him.
