Outside of not gonna happen?
There is something to be said for that on some nights, but if you did, then you would have not 1, not 2, but 3 tweener forwards on the bench all clamoring for the same minutes, and nobody even remotely big. (Of course having Skinner on the bench doesn't matter anyway if you are not going to play him.)
In any case though, fact of the matter is that Brian Skinner is a PF. He's 6'9". That's not even especially large for a PF, let alone a center. And tonight the Cavs will be trotting out a 7'3" pivotman in Big Z. So probably not a night when starting Skinner would produce great results. He's looked overwhelmed in the past by the really big guys, and Ilguaskas certainly qualifies.
