I'm glad a foul was not called, because Dirk should have either drove or jumped into Bowen after the pump fake to draw an easy foul. Then Manu or (gasp) Finley would have hit the game winner.
That being said, I think there was clearly contact on the lower arm, and a foul could have been called legitimately. I'm glad the refs let them play instead of calling the foul.
