Yeah, I'd give that one to Erskine. Boulton might have tossed one or two more, but it seemed like Erskine landed plenty. Damn, some of those were lasers! Surprised it didn't reflect it in Boulton's face. Probably by today.
Boulton did not return to the ice after the fight and Erskine went on to score the game winner. I would think Erskine is a clear winner in the overall scheme of things.
