as it is written today it is a goal. there is no distinct kicking motion. did he twist his foot to allow the puck to deflect/carom off it? yes. did the puck rebound in the net? yes.
everyone does it. they play the bounce. until the league changes the rule we will see more of this. until they change it so everything from the ankle down doesn't count, the players will find ways to bend the rules. it's what guys do to get the advantage. take away deflections from the ankles down and it takes away an area of the body guys can use to redirect pucks.
The smirk and giggle on his face when he was on the bench watching the replay was all the evidence Toronto needed. They should have reviewed that instead of the goal itself.
I feel like every time I think a call is pretty obvious, it goes the other way. Maybe I just don't know the rules as well as I thought I did.
