I've been trying to watch the video objectively ... I'm not a fan of either the Leafs or the Canadiens, and don't want to see a player get hurt.
But can you explain what, in your view, is "bullshit" about the play?
It didn't look like a purposeful knee-on-knee, in fact it wasn't knee-on-knee per se, it was more like Laine's shin went under Pare's knee and bent awkwardly. Pare looks like he's just stepping into a bodycheck as Laine tried to dangle him and the other Leafs player. What was Pare supposed to do? Stepping aside to let Laine past seems like the only option to avoid this outcome unless you see another option that would have rendered Pare's approach non-bullshit.
I know nothing of Pare, not going out of my way to defend him. I don't hate Laine. I'm just honestly saying that based on what I see and my own (albeit low level community club) hockey experience I don't know what else Pare was supposed to do there.
