Well, that didn't take long.
Former UMD Bulldog Jay Rosehill, making his NHL debut Thursday night, waited all of two shifts before dropping the gloves for the first time.
At 10:55 of the first period, the Maple Leafs left winger (a defenseman until a recent position change) got into it with Montreal veteran Travis Moen. Rosehill's first regular season fight was Moen's 47th, but it doesn't appear that experience was much of an advantage.
There may be bias here, but Rosehill is a clear winner. You can actually vote on the winner at the Hockey Fights website.
