The Calgary one is the only one where he was actually given an embellishment penalty, it's been talked about enough. His stick went up in the air, if that's embellishment sure, whatever. I don't get the Ottawa one though. He could have just simply lost balance, the game is played on skates and ice you know. You basically need to be reading his mind to know if that was a dive or not, and if the league had that power then they should probably be putting it to better use.
