That was the 2nd - or 3rd - game this season they've blown in the last minute.
As in past seasons they play too passive with a lead, late in games. Allowing the opposition (with the extra man) to take shots unchallenged. Then not clearing crease of players.
I also wonder what's going on with/between Gaudreau an Vincent. Gaudreau doesn't look like he's comfortable, or really engaged in the game. He should be driving play when he's on the ice. It was several shifts before he played in the OT last night.
