You breathe on Hasek when playing against the early 90s Sabres and you'd have a riot. Now you can knee drop a goalie and the only retribution is a 20 page thread on HF full of people calling you names.
Make him stop playing that way. If you beat him up and he continues to do things like this, then the Calgary goalie or Little Johnny can be attacked. This wasn't something where a suspension is in order because you can't prove he did it on purpose but, you know, he isn't a player that is going to try and cushion his fall or even avoid falling on the goalie. If you push him around the goalie, he will fall into them. Tale as old as time except you'd pay for stuff like this back in the day.
To be fair, I'd want any Kings player in front of the net to fall on the other team's goalie if shoved as well. Hell, I'm just excited to see that some of the Kings players seem to know where the front of the net is this season. Baby steps.
