Here's a crazy idea, once Doc goes to the bench. Play Ray at PG, that's essentially what was happening when Eddie House played. House brought it up, but Ray would get the ball early in the shot clock.
You put Ray at the top of the key, set him a pick, and either play pick and pop with him and KG or PJ, or let him drive to the hoop and pull up or finish. It is more similar to the offense he ran in Seattle. He's not a spot up shooter, he's a scorer, who can still create his shot.
