This offseason, the league needs to review the flagrant one rule for excessive contact, if said contact was inadvertent. For instance:
Theis elbow on Lowry in game 1 (I believe), where Theis was moving from side to side, while his arms were in a defensive position. The contact was purely accidental, but a flagrant one was called on Theis and resulted in a free throw.
Last night, Tatum drove into the lane, and the natural motion of his arm accidentally hit a Toronto defender.
I know there's one or two more, because Toronto is constantly complaining to the refs. I know the Celtics complain too, but Toronto seems to take it to another level.
