Cotter’s second goal of the game extended it to 4-2 at 13:38. He finished a pass from Noesen on a 2-on-1 rush.
Wilson cut it to 4-3 at 1:35 of the third period, scoring from the slot off a pass from McMichael from behind the net.
“I thought our line was good,” Wilson said. “We got a lot of forechecked pucks back. [Dubois] is so good with the puck, fending guys off. [McMichael] was a force and obviously made an amazing pass to me. It’s fun playing with those guys, and I think we got better as the game went on.”
Dawson Mercer scored into an empty net with eight seconds remaining for the 5-3 final.
