I can't tell to be honest. I mean the goalie does look behind him but with no sound to hear a whistle, no ref in view to see what he called and no picture of the puck. There's nothing more to go on than a Tiger with his arms in the air.
Only thing I can figure out is the puck was going to go over the net. I cannot tell where the stick made contact with the puck or if it was high or not. It looks to be a call that could've gone either way.
