What do you think Samson Johnson's stats would be if you doubled his minutes and replaced all the other good players with bums? I feel like 5.5 and 3 can become something like 13 and 8 if you really forced it.
And Johnson already averages more blocks than him. Johnson is shooting 72% from the field. Let him put it up more and let it drop to 58%, he'd probably come close.
(Probably wouldn't match the rebounding, but who knows).
All this to say: if the staff wants him, fine. They've earned trust. But my basic position is to stay the hell away from anyone who played for Payne.
