To answer the question this headline poses, the Florida Panthers can beat the Boston Bruins in the first round of the NHL playoffs.
The word "can" has a lot of heavy lifting to do considering the Bruins finished with more 43 more points than the Panthers during the regular season. To put that in perspective, a team with 43 fewer points than the Panthers would sit a 49. We haven't seen a points total that low in a full season since the disastrous 2016-17 Colorado Avalanche.
So there's a significant gap here.
