Ehrhoff fired a wrister from the slot over goalie Anton Khudobin, who anticipated a low shot and went down early. Cody Hodgson added an insurance goal less than 3 minutes later when he tipped in a pass from Tyler Myers.
Myers began the comeback 2 minutes into the third period, tying the game at 2 by backhanding in a rebound after Khudobin stoned Jochen Hecht on a 2-on-1 break.
The goals completed a stirring comeback for Buffalo, which trailed 2-1 going into the third. Entering the game, Boston (8-2-2) had outscored its opponents 15-5 this season in the final period.
I downplayed the first one because I thought it's just a hockey game. We just want to win the game; it's against our rival and we want the two points. I downplayed it, but now having gone through the first one I look back and say, 'Geez, that was really cool.' I think as I've grown a bit older I've got a lot more appreciation for what we're allowed to do every day.
