He did it yet again on Monday, a moment that will live forever for him and the Boston Bruins. This time it came at 5:21 of the third period to put the Bruins ahead of the St. Louis Blues, complete their comeback from down two goals, and push them to a 4-2 win in Game 1 of the best-of-7 Stanley Cup Final.
Game 2 is at Boston on Wednesday (8 p.m. ET; NBCSN, CBC, SN, TVAS).
This, after all, is a player with seven goals in 30 games in the Stanley Cup Playoffs, a player with 14 in 154 regular-season games.

Those goals were his first and second in the NHL.

There was the game-winning goal in the third period at the 2019 Bridgestone NHL Winter Classic against the Chicago Blackhawks. There was the Game 7 goal against the Toronto Maple Leafs in the first round that extended the lead to two. There was the third-period goal in Game 4 of the second round against his hometown Columbus Blue Jackets that also gave Boston a two-goal lead on the way to a win that tied the series.
There was the goal on Monday, to go along with the pass that Bruins defenseman Connor Clifton knocked in for the first goal against the Blues at 2:16 of the second period to cut it to 2-1.
"He's been doing it all year," Bruins center Patrice Bergeron said. "That line got us going, obviously, and got us the game winner. We're a team that's relied on everybody all year. Tonight was another good example."
