I haven't noticed anything on the net about Hockey East using two referees per game. One thing the change seems to have done, in my opinion, is reduce grandstanding by the linesmen. "Drop the puck" cries are fewer, and the game progresses quicker. Also, in last Sunday's Dexter Classic championship game between Maine and Brown, a friend with a stopwatch tells me that Maine went 45 seconds with too many men on the ice, including a few seconds with TWO extra men, when the refs finally saw the transgression and whistled it.
