It's wholly conceivable that each team scores at least three goals in this game. 
The Canucks have produced at least three goals in eight of their last 10 games. Toronto ranks 17th defensively giving up 2.9 goals a game. The Maple Leafs are a bottom-eight team killing penalties. 
Vancouver, though, has the worst defense in the NHL yielding 3.9 goals per game. So it's no surprise the Over is 8-3 in Vancouver's last 11 games.
Toronto just buried the Canucks, 7-3, two days ago at home. The Maple Leafs had plenty of energy having been idle the previous four days. They should have lots of energy for this one, too, since it's just their second game in six days.  
The Maple Leafs are the fourth-highest scoring team in the NHL averaging 3.6 goals. They had scored three or more goals in 10 of their last 11 games. 
Austin Matthews is making an early case for MVP honors having scored at least one goal in five consecutive games.
