I would 100% take a dive if I felt the stick graze my chin. While I am not one that is necessary for embellishing, you need to make something happen in the end of the game. A stick going near someone's face, should be something that is pretty easy to see and should not be missed by the referees regardless. So in that moment I try to do what I can to get a penalty called for my team. Having a man advantage is so huge for a team in a tie game. It also allows the more defensive players to catch a breather. Even if our team does not score on the power play, we would be able to be in better shape as the clock winds down and if we have to go into overtime. Because the stick was near my chin, I would not really worry about being called for embellishing as the stick was at my face anyway. I believe we would get the call and score on the man advantage
