As the NHL Playoffs approach, a review of impactful trades from the recent trade deadline highlights key players who can significantly influence playoff outcomes. The Ottawa Senators made a notable move, acquiring Dylan Cozens from the Buffalo Sabres, which has revitalized his game, evidenced by his 11 points in 19 games since the trade. Cozens brings physicality and skill that the Senators will need alongside their young core in the playoffs. The Toronto Maple Leafs acquired Brandon Carlo from the Boston Bruins, a stay-at-home defenseman who enhances their defensive stability and allows Morgan Rielly to be more offensive. His contributions in front of the net will be crucial as playoff intensity rises. Meanwhile, the Florida Panthers secured Seth Jones from Chicago, whose puck-moving abilities are essential for their defensive lineup, especially with Aaron Ekblad out for an extended period. Lastly, Yanni Gourde's return to the Tampa Bay Lightning promises depth and defensive responsibility, amplifying their playoff roster's strength. Each of these players could be pivotal as their respective teams pursue the Stanley Cup.
