New York Islanders: Jordan Eberle, F -- The Islanders right wing had his lowest point total in a full season (37) but finished strong with five points (four goals, one assists) in the final five games mostly skating on the top line with center Mathew Barzal and left wing Anders Lee. If the lineup placement sticks, Eberle could play a valuable role in the first round against the Pittsburgh Penguins; he had two goals in four games against them in the regular season.
Pittsburgh Penguins: Justin Schultz, D -- The Penguins defenseman missed significant time this season with an ankle injury but had 15 points (two goals, 13 assists), six on the power play, in 29 games. He'll be relied upon to contribute offensively on the second pair with Olli Maatta and second power play. Schultz has 25 points (five goals, 20 assists) in 48 playoff games.
Tampa Bay Lightning: Mikhail Sergachev, D -- The Lightning defenseman flew under the radar this season with 32 points (six goals, 26 assists) in 75 games after scoring 40 points as a rookie. The decline in production came despite Sergachev skating more than two minutes per game (17:55) more than last season (15:22). If Sergachev takes advantage of the additional ice time, he could be their second-most productive defenseman behind Victor Hedman and pay dividends over multiple rounds.
Toronto Maple Leafs: Kasperi Kapanen, F -- The Maple Leafs right wing had a breakout season with 44 points (20 goals, 24 assists) in 78 games mostly skating with elite center Auston Matthews at even strength. Kapanen is expected to start on Matthews' line over William Nylander against the Bruins in the first round and could draw more favorable defensive matchups than the top line of forwards John Tavares, Mitchell Marner and Zach Hyman.
Washington Capitals: Jakub Vrana, F -- The Capitals wing had NHL career-highs in goals (24), assists (23) and points (47) in 82 games. Vrana is expected to skate on the third line with center Lars Eller and wing Brett Connolly, who also had a career high in goals (22), against the Hurricanes in their first round. Vrana had eight points (three goals, five assists) in 23 playoff games last season and has additional room for growth, especially if he's moved back to a line with either center Nicklas Backstrom or Evgeny Kuznetsov.
