If you told Toronto Maple Leafs fans their sixth- or seventh-best defenseman would be significantly responsible for two straight overtime goals in the first round of the Stanley Cup playoffs, you would’ve been asked to immediately take a sobriety test.

The Leafs boast some of the biggest names in hockey, but on Thursday someone new became "the king of Toronto for a night."

Instead, it was a 26-year-old, third-pair defenseman from Laval, Quebec, who proved to be the difference-maker by beating goalie Linus Ullmark at 1:19 of overtime to give the Maple Leafs a 3-2 victory against the Ottawa Senators in Game 3 of the Eastern Conference First Round at a raucous Canadian Tire Centre on Thursday.
