I was at the other end of the ice from you. ^
The first Dartmouth goal was through the (gaping) five-hole. I was concerned about that given what has been said here about Petruzzelli's confidence and the team's trust in him! The second went underneath him with, as you say, a lot going on in front. I think the team's protest was probably goalie interference (Thinking he was pushed? He kind of fell backwards into the net as the puck went in.).
What did you see of our non-goal toward the end of the third? To me, it looked like the puck was directly in the back of the net and bounced out. The Dartmouth fans right next to me thought it was in, as did their friend who came over to check what they had seen from our angle. No goal light and play continued without incident.
I didn't think there was really any sustained puck possession from either team all night, other than on the power play.
