Dany Heatley has received a two-game suspension for delivering an elbow to head of Steve Ott on Tuesday, but Douglas Murray got away with a shoulder hit to the head of Loui Eriksson and an elbow to the head of Tomas Vincour in the same game.

On the same night, Brad Marchand delivered a blindside elbow to the head of R.J. Umberger and is awaiting a telephone hearing Thursday, which means a suspension of five or fewer games. As NHL general managers wrapped up three days of meetings in Florida on Wednesday, the loudest voice to address an alarming increase of hits to the head is coming from players like Vancouver Canucks defenceman Kevin Bieksa.

Yes, Rule 48 to penalize lateral or blindside hits to the head with supplemental discipline is slowly working — Matt Cooke and Mike Richards turned away from delivering those hits recently — but suspensions can only go so far. An alarming 72 concussions this season speak to a growing lack of respect.
