Torey Krug executed a ideal zone entry on Boston's first power play - facing little to no resistance from the Leafs - and then passed to Brad Marchand, who beat Leafs goalie Frederik Andersen for the first goal at 5:28 of the opening period. If one or two others can hold their own and gain confidence in this series, the B's are in good shape.

David Backes put the Bruins ahead for good with Boston's second power-play marker at 15:43 before their top line extended that advantage. With Marchand's work along the boards, Pastrnak found an open lane to receive a pass, and after the first attempt was stopped, a second shot found it's way past Andersen to make it 3-1. From there, the Leafs started to gain momentum as the first period wound down.
Toronto killed off two penalties to start the third, but Kuraly made it 4-1 when he batted the puck out of mid-air at 7:41. Toronto had the league's second-best power play, which led to the third-ranked offense with just shy of 3.3 goals per game.

Toronto, which fancies itself a legitimate contender for the Stanley Cup Final, was clearly none too pleased about getting dressed down to the tune of 5-1 (4-1 at the time of the hit).
Last year, the Leafs weren't expected to make the playoffs so it was a bonus, but fans are expecting a lot more from them this year, and are hoping for at least a second round appearance.
