Play 1: I saw no foul on the defender.
Play 2: Won't argue with call but I do not understand mechanic. There was no stop clock signal, as has been dictated by JD all year, and pointing is not a mechanic listed in the rule book. Could have just gone fist in the air, followed by hand behind the head or punch (but then again I am not on TV so surely cannot judge)
Play 3: I could not find a defensive foul.
