I'm not so sure about that, but it's very hard to separate the relative merit of each player, especially Eddie Gerard.At first glance George Boucher was actually more important to the dynasty than Gerard, even ignoring 1927.Is that the case? Hard to say.
By going game to game, and trying to come up with some sort of "three stars of the match" system based on the summaries, Benedict would come out ahead of Gerard IMO (all of this is obviously debatable, as it is hard to assign the three stars in many games).But Gerard was a defensive defenseman, and his style wasn't suited for high praise in any given game; he was not spectacular like George Boucher nor was he the queen of the chess board like Nighbor, nor was he a goalie who can stop pucks and have his performance noticed.
Seems too close to call.
