Cormier isnt really the kind of player to try and think of tricks to get the upper hand. He knows he has a lot of raw skill and an incredible amount of speed and always tries to use that to his advantage. He does get called out a lot for embellishments when he falls, but people dont realize the speed at which the game is played. When you move that fast it doesnt take a lot to lose balance and Cormier has that happen a lot. He's fast, light on his feet and can have some difficulty staying upright through minor contact. I don't really think there's anything the league needs to do to crack down on trickery though. Anything thats clearly an infraction will be called as such and a lot of these tricks really dont fall into that category. The onus in these situations is on the players to be concious of the common tricks and to find ways to not get beat by them when they happen during a game.
