Matthew Knies is the definition of a playoff performer with the Toronto Maple Leafs. At 22 years old, Knies is already making massive blocks, scoring crucial goals — including his netfront power play marker in the third period — and playing a team-high 22:19 in Game 1 against the Ottawa Senators.

The Maple Leafs and Senators got into multiple scraps late in Toronto’s 6-2 Game 1 home win Sunday night in the first round of the NHL playoffs. At the end of an ugly night in which Ottawa gave up three power-play goals, the Senators and Leafs started pushing and shoving each other after a whistle with 43.7 seconds left in the game.
