I think it was jack_duck that posted a few exhibition results where he'd put his starting PG at the 5 and starting C at point. He had several examples where the actual pg racked up several assists and the C rarely turned the ball over. So while not completely relevant to the issue at hand (though it does address one of your questions in the ridiculous exchange with CS), there was some evidence that the engine will find the guy with the best PG skill set and run the offense through that player, regardless of which position the player was actually playing.
