Against the Catamounts, the Crimson were called for 11 penalties, including three for hitting after the whistle, two for unsportsmanlike conduct and another pair for roughing. And on three of the six power plays that ensued, Vermont found the back of the net.

Saturday, on Senior Night for the Crimson, the team took fewer total penalties and managed to kill off all of the resulting power plays. Dartmouth had a man-advantage eight times during the game, including two extensive five-on-three opportunities, and came up empty every time. And the difference between the nights was not due to the relative strengths of Vermont’s PP versus Dartmouth’s, it was due to the Crimson’s play in the penalty kill and between the pipes, according to Mazzoleni.

“I thought [Dartmouth] did a good job of moving the puck, Dov was just very good in goal,” he said.

Indeed, Grumet-Morris made a significant impact; he stopped only 20 of 25 shots on Friday but stopped all 40 he faced on Saturday. And fully half of those shots came with Dartmouth on the power play.

But more important than the number of attempts was the quality of the shots that the Big Green was allowed—nearly all of its came from the perimeter, even when Harvard was down two men on the penalty kill—that was truly different than the Vermont game. And the credit for that belongs to a penalty-kill unit that, despite playing without its top blue-liner Welch, shutdown one of the ECAC’s best power play units and its second-best offense.
