I only was able to watch part of the game, but Quis has one play early on that made me think he's been taking notes from Pierce. Had the ball near the baseline, maybe 15 feet from the basket, defender got close to him, Quis thrust his arms up in a shot "attempt" but really just initiating contact with the defender. Foul called, hit both free throws.
Play we've seen Pierce do hundreds and hundreds of time. Just smart ball - the defender's in bad position, so force the contact since the refs have to call that a foul.
