So, how long will the suspension be? I see two trains of thought, here.
1. With the shadow of the Steve Downie incident looming in the background, and Boulerice's history of similar incidents from his junior days, Colin Campbell will throw the book at the guy, using Downie's 20-game suspension as a floor. The NHL wants to nip this thing in the bud, and Boulerice is the type of goon that the league can easily suspended for a long time.
2. Boulerice might get 10 games, at the most. Think about it ... Kesler is not nearly as injured as McAmmond (who is out for a long time), and the media coverage of this hit isn't generating nearly the same firestorm as the Downie incident. The NHL seems to tailor its suspensions on media fervor (Bertuzzi, McSorely, etc) and not on anything else logical. Besides, we know the NHL isn't 'supposed' to consider non-NHL incidents in handing down their punishment, so it'll be another slap on the wrist from the NHL's head offices.
In the end, I hope Boulerice is not playing hockey until AT LEAST the New Year. This stick-work is a lot more dangerous than Downie's hit, and much more premeditated. Boulerice is the very definition of a talentless goon, and the game, and fans, won't miss him a bit.
