we beat teams we are not supposed to beat and lose to supposedly inferior teams. I argue that the opposte is true. Rockets, Spurs, grizzlies and Pistons have one thing common, big physical centers\frontcourts. We won handily against them because asik is stronger than drummond, duncan, howard and gasol, they also dont have answer for a stretch 4 like Ryno.
celtics, sixers are bad match ups because their centers rely on speed instead of physical force. if Omer didn't have stone hands he would feast on these teams, unfortunately this is not the case.
Against teams like celtics i believe withey is useful. Withey might not have ajinca's offensive repertoire but he can finish in pick and roll and he is not a foul machine
