No that's the most ***** ***** ass thing I've ever heard. When a goon goes after you your teams own fighter then gets involved. Its as simple as that. The ***** slashing and hacking crap has to go.
There was no fighter on the ice for Toronto. The forwards were Ashton, Bozak, and Kessel. Who exactly should have dropped their gloves and fought Scott when he elected to jump Kessel? What good would it have done for them to go after him once he got out of the penalty box and Kessel had has his ass kicked and potentially been hurt?
This isn't like when Maguire jumped Yzerman and Probert was right there to get instant vengeance. It's all well and good to say "fighters fight fighters" but that's not how the situation developed. Kessel was entitled to use a force multiplier to defend himself.
