2 completely different situations. Mclennan's was so obviously premeditated that the nhl had no choice but to come down hard on him. I believe that Jim playfair(Calgary head coach at the time) was also disciplined by the nhl.
This was given a 5-game suspension and totaled $125,000 in fines back in the playoffs of 2007 (prior to suspension crackdowns). Both plays were malicious attacks against the opponent using the hockey stick as a weapon, although McLennan gave more of a slash than a spear. Personally, I think these two cases are fairy similar, but everyone else is free to make their own judgment. Nonetheless, if the league thinks the above penalty is worth 5 games, in the playoffs no less, than I don't think its reaching to see Franzen get one game, or maybe even a fine. Granted, there have been a few notable spears in recent memory which didn't result in suspensions, so if he gets nothing I wouldn't be surprised at all. I'm not about to try to predict the outcome of this situation.
I still stand by my belief that this type of behavior is a joke and should be punished. If Franzen wants retribution for a hit he doesn't agree with, then he needs to do it like a man and use his fists, face to face with his opponent. Otherwise get on with the game because frankly its embarrassing and a waste of time.
Franzen's situation was a quick second reaction to dirty hit from behind. the 5 minute major and game misconduct (which was the right call) should be the only discipline he gets. I suppose a fine will be in order as well.
