He was doing that on a 5 on 3 Powerplay splat. When you are shorthanded two guys you can't have one of the three get tied up with a guy in front. You have to play a rotating triangle to try and defend.I think Making a Rule for that is weak. what ever happened to the defenense men clear men out from in front of the crease. if the defense was doing its job they wouldn't have to worry about a fool like avery doing some that childish.
