The NHL is expecting pulse-pounding action on Sunday with three of the five games set to be played between two teams currently in playoff position. The Penguins will play the Bruins, the first-place Jets will take on the first-place Capitals and two division rivals will square off as the Golden Knights take on the Flames. Those games will be front and center for both casual hockey fans and those that are looking to win big in NHL DFS tournaments and cash games on Sunday. And stars like Brad Marchand, Evgeny Malkin and Braden Holtby are among the more expensive options for Sunday NHL DFS lineups. But before you make your NHL DFS picks, be sure to check out the optimal NHL DFS strategy from DFS millionaire Mike McClure first.

McClure is a DFS professional with nearly $2 million in career winnings. He's also a predictive data engineer at SportsLine who uses a powerful prediction model that simulates every minute of every game 10,000 times, taking factors like matchups, statistical trends and injuries into account. This allows him to find the best NHL DFS values and create optimal lineups that he shares only over at SportsLine. They're a must-see for any NHL DFS player.

On Saturday, McClure was all over Penguins wing Zachary Aston-Reese at $3,500 on FanDuel. The result: Aston-Reese scored a goal against the Blue Jackets -- returning almost 17 points and nearly 5x value. Anyone who rostered him was well on their way to a winning night.

For Sunday's NHL DFS slate, we can tell you McClure is high on Penguins center Sidney Crosby at $9,500 on FanDuel and $7,200 on DraftKings. Crosby has 14 points in his last seven games and is now up to 87 points in 65 games this season. On Sunday, he gets a matchup with the Bruins that he's historically feasted on. Crosby has 52 points against Boston in 38 career regular-season games, so be sure to get him into your NHL DFS lineups on Sunday.

McClure is also recommending Flames defenseman Mark Giordano ($6,600 on FanDuel, $6,200 on DraftKings), who has 62 points in 66 games this season.

Giordano's ability to move the puck has made him a bonafide top-pairing defender who is valuable on the power play and can also kill penalties. And a huge offensive season has seen him make an impact in all three phases, with eight goals at even strength, three goals with the advantage and even three shorthanded goals. With a short schedule on Sunday that doesn't have many offensively dynamic defensemen, you won't want to miss out on Giordano's potential productivity.

McClure is also targeting an undervalued player who is set to explode for huge numbers on Sunday. He's a huge steal at his price point, so this pick could be the difference between cashing and going home with nothing. You absolutely need to see who it is before setting your lineups.
