In recent games, the Bruins' goalie, Jeremy Swayman, has been causing trouble for the Toronto Maple Leafs. He's won six straight games against them, including five this season. His stats speak volumes: a .964 save percentage and 1.70 goals against average in this year alone.
However, Toronto's struggles aren't just about Swayman. They've had plenty of chances, especially on power plays, but they haven't capitalized. In Game 3, they had five power plays and couldn't score on any of them.
Throughout the series, they've only managed one power play goal out of eleven opportunities. That's not good enough, and it could cost them the series if they don't improve.
