The Maple Leafs had a power-play percentage of 25 percent last season, which was second to the Pittsburgh Penguins (26.2 percent). In 2016-17, Toronto's power-play percentage was 23.8 percent, which ranked second to the Buffalo Sabres (24.5 percent). This is an improvement from their performance in 2015-16, when the Maple Leafs ranked 29th with a power-play percentage of 15.4 percent.
Toronto's goal is to spread the scoring evenly over two power-play units. Over the past two seasons, Marner had 48 points (12 goals, 36 assists), forward James van Riemsdyk had 39 (17 goals, 22 assists), Nylander had 38 (14 goals, 24 assists), forward Nazem Kadri had 36 (24 goals, 12 assists), Matthews had 34 (13 goals, 21 assists), and forward Tyler Bozak had 31 (10 goals, 21 assists). Defensemen Morgan Rielly had 30 points (two goals, 28 assists) and Jake Gardiner had 28 (three goals, 25 assists).
The Maple Leafs will receive a boost from forward John Tavares, who led the New York Islanders with 48 power-play points (19 goals, 29 assists) over the past two seasons, but Toronto lost van Riemsdyk to the Philadelphia Flyers and Bozak to the St. Louis Blues as free agents.
