Maybe we can have every single player who threw a check arrested for assault too.
That's just being ignorant. In NA law engaging in contact sports is implicit consent to engage in physical contact that could/ would be considered criminal outside of the sport.
Hell in canadian law there's provision for consensual fighting to be legal. One fun little piece of that law however, is that a fight cannot be consensual if one of the combatants was "backed into a corner" and forced to react in self defense. So legally speaking Eller did not engage in a consensual fight, he defended himself from an assault. But the NHL isn't a courtroom.
Summary of events:
Ellers celebration- pretty tacky, don't blame the Bruins for going after him
Marchand's way of starting the fight- gutless and cowardly, I assume anyone that defends it is also a gutless coward
The fight- good on Eller for standing in, he had no idea what he was doing and size notwithstanding was starting off at a huge disadvantage (helmet off, Marchand had way better grip, and the initiative) but props for trying.
The aftermath (Rules)- fine with the penalty and no supplemental, Marchand didn't connect with the early punches so no real harm done but if he does and Ellers goes down and smacks his helmetless head on the ice (which Marchand calculatedly tore off).. we're looking at Bertuzzi 2.0 and the real end of fighting. Thank god Marchand threw pillows
The aftermath (on ice)- hopefully Marchand gets jumped and fed. Live by the sword, die by the sword. The code doesn't protect those that don't follow it.
