Grizzlies owner Robert Pera plays in a regular pick-up run and according to those who have seen him he’s got some game — he has a jumper from the outside and some hops around the rim to the point he used to be able to dunk. That doesn’t mean he’s beating Tony Allen one-on-one. But the two are playing this Saturday in Memphis for charity. It all started on twitter. The best part — Zach Randolph is going to be the referee for this game.
