They will also need to take advantage of their special teams on both ends. The PK has been stellar this season which will be a great help shutting down the Leafs stacked powerplay but the Bruins PP will need to step up as they have struggled lately and cannot afford to miss on key opportunities against the Leafs.
A major part of beating the Leafs will be if the Bruins are able to shut down one of their top two lines. The Leafs have a stacked first two lines and if the Bruins can shut down at least one of those lines, they will have a much easier time taking care of business.
