I know this isn't going to be a popular thing to say, but it wasn't a dirty hit. if you watch the replay, what part of Mccloud's body hits kronwall's head? It was his thigh. kronwall's head went sideways into the boards. That is why his ear is cut up. Now it is physically impossible for those 2 things to be true in a hit from behind.
I understand the climate of sports today, and no one wants to see anyone get hurt. But players need to be more aware of where they are in todays game. Darren Elliott during the intermission break all but refused to call it a dirty hit, in fact he was far more focused on the other hit right behind the play on Glendenning.
Mickey Redmond talks about this all the time. Players put themselves in dangerous positions far to much and are not allowed to protect themselves anymore. a bi-product of far to many rules in todays game.
Now will McCloud get suspended? yes he will. it would have been a boarding call if Kronwall hadn't turned, so a dangerous play anyway.
I didn't read your whole post, didn't need to. Regardless if Kronner turned or not he was still getting hit from behind. Blindsided hits are dirty hits. McLeod saw the numbers the entire time and never let up
