Typical Boobgaard cheap shot (this one aimed at the knees of an opposing player) starts this one. What a low-watt caveman ass. He wins (he'd better, he's twice Cowans size and Cowan isn't a great fighter) but he's still the least classy player in hockey.
You can tell that Boggey isn't taking the fight all that serious, look how long it took him to drop the gloves. I'm pretty sure he felt bad for Cowan, having to step up for his bitch-ass teamates. Had Boogey wanted to, he could have really hurt Cowan, but I don't think he wants to be known as the guys who ends peoples careers (having realized what he's capable of at the expense of his current teamate last year). He did his job, and did cowan a favor.
And no, it was not a hit that Cowan needed to stand up for. Boogey never even touched the guy.
