I agree there's a serious problem with the suspension he handed to Keith. I'm ok with not penalizing hits that injure players overly harshly so long as the hit was a HOCKEY PLAY that got out of hand, such as shoulder coming up to the head or what have you.
But this Keith hit which was a blatant attempt to hurt Sedin when he didn't have the puck and was a completely illegal hit and just not a hockey play.
Neither was the Bourque hit on Backstrom.
Both Keith and Bourque should have had to sit for seriously 25 games for that (and I'm not exaggerating for effect). Again, I'm not a soft hockey-guy, I actually am all for no suspensions for hits to the head that just happen to happen throughout the game due to player miscalculation.
But when you are throwing a disgusting hit with intent to injure when the guy doesn't even have the puck: that doesn't belong in hockey and neither should the offender for a long period of time.
