I'm not entirely sure that the moderate-to-low level of force of McMann's swing (which was dumb but certainly wasn't an intentional head shot and primarily just hit the guys shoulder) is worth more than a game misconduct and a max fine, but I won't really lose any sleep over a 1-game suspension.
That's what I thought - stupid/careless/dangerous but more of a love tap than a blatant intent to injure. No previous suspensions (unless I'm forgetting something), not known as a dirty player. Then again, he's a Leaf so probably 5 games.
Seriously, I think 2 games would be excessive, but he'll probably get at least 1.
