Boston owned Toronto during the regular season winning all four games, including capturing the last two meetings by three goals apiece in each game. 

Toronto has a sad playoff history and enters this opening game matchup on a four-game losing streak giving up 22 goals during this span.

Defense always is a key especially in the Stanley Cup playoffs. The Bruins ranked sixth defensively. They held Toronto to one goal each during the previous two meetings. 

The Maple Leafs were 21st defensive and 23rd on the penalty kill.
