Well, that's a good litmus test on NHL and Colin Campbell. Let's see how hypocritical NHL will react to an identical 'little push'. All the bets are that nothing will happen.
That's what Colin Campbell will say: "But Mike Fisher didn't break Kaleta's clavicle! It's ok to push people into the boards if they won't break anything"
From the previous post:
Campbell knew Ovie was behind him, in fact took a second look just before the hit. He in no way prepared himself to be hit (or even shoved?), which seems to be commonplace these days in the NHL. There was a time in hockey when D-men would 'lunge' towards incoming hits with their shoulder, mitigating much of the impact.
Are we really going to remove all responsibility from players who have the puck in terms of awareness? Can you hit anyone anymore?
Reader's comment from The Spin
I think with Kaleta it looked more like a dive to get Mike Fisher out of the game. Just like with Campbell and Ovechkin there's a quick look back at Mike Fisher and then perfect dive into the boards. No lunging back at Mike Fisher. Mike Fisher pushed him directly from behind, Ovi did it sideways. You can see Kaleta going head first and then making an acrobatic move and going to the boards shoulder first.
NHL Archive: "Mike Fisher is ejected, Kaleta appeared to be fine until he saw the penalty call and appears to have embellished, something he is known for. From a game between the Ottawa Senators and Buffalo Sabres on Friday, March 26th, 2010 at the HSBC Arena in Buffalo, New York."
Now NHL has opened a whole new can of worms, see more diving that will lead to more game misconducts. If they extend it the playoffs the players will intentionally dive to take the opposing team player out of the game.
