Yes, true, I'll buy that to a point. But my team this year had the Conference Player of the Year (I can't take credit for that), a guard. At PG he consistently scored less than at SG and fiddling with distribution didn't change that one bit. Sometimes he had disproportionately high distribution at PG (when the defender wasn't so hot) and he still did not score like he did as a SG. His big scoring consistently came as SG with no higher distribution. In fact, in games when he was at PG it was whoever started at SG who often became a good scorer. I became convinced that SG is a more important scoring position and PG a more important flow position, all things being equal. I know there are other possible explanations and I'll still be keeping an eye on it and experimenting, but that was my experience this year.
