“I thought we played really well in the first two periods,” sophomore defenseman Dan Ford said. “[But] in the third period we came out a little flat and didn’t stick with what brought us success in the first two.”

The Terriers took advantage of that flatness and cut the deficit to one when Connolly put back a rebound with 11:09 to go in the game.

“I feel like their second goal was kind of a momentum shifter for them,” Fallstrom said. “I think we had the game under control up until that point, and after that they really got going and started creating a lot of opportunities.”

Soon after, Rosen tied the game with his first goal of the year following a scramble around the Harvard crease.

In the overtime, after a Crimson neutral zone turnover, Michalek saved a Connolly attempt from the right but left the rest of the net exposed. The rebound went directly to a trailing Noonan, who was able to easily put back the rebound to give BU the win.

“We probably stopped attacking as much offensively,” Ford said. “That just led to them having more puck possession, and they put a lot of pressure on us and were able to get two goals.”

Alex Chiasson assisted on the final three Terrier scores, joining Clendening with three assists on the evening. Everson had two assists for Harvard, while Michalek made 30 saves in defeat.

It was the second straight 4-3 win over an intra-city rival for BU, which was coming off a victory over Northeastern. The Crimson lost its second straight after falling to No. 14 Union at Fenway Park Friday night.

“We definitely learned from this game that when you’re protecting a lead in the third period, you’ve got to play smart, but you’ve still got to attack offensively,” Ford said. “We kind of stopped doing that and played a little more passively. There’s too much time to just sit on a two-goal lead against a good team for two periods like that.”
