This seems more because of the result of the hit rather then the push itself. I think it is careless to push a guy that has all his weight on the inside of his skates, getting ready to take the corner around the net, but it happens all the time and if Campbell jumps up then nobody would be talking suspension. This is one of those times where because of WHO was doing the pushing, it probably hurt OV because it gets more attention.
My mantra is getting old, but I'll keep saying it, that I want the players to deal with "problems" and the NHL to stay the fuk out of the game. They are slowing legislating physical play out of the game and pretty soon we are going to have womens/beer league rules where you can only rub a guy out but can't put your shoulder into them.
