Indiana Miami: Game 3 elbow

I've switched my opinion on this play several times. Watching the game live, I thought it was a flagrant foul (NFHS intentional). Seeing the replay it looks as though Wade is doing a "swim move" to get around Stephenson. This makes me think the contact can be considered incidental. However, Wade could have run around him without jumping into the air, and without contacting Stephenson's head. So I am pretty back and forth on it. My current opinion is that I would call a NFHS intentional foul because this contact was unnecessary.
