Kaplan recorded 18 points (10 goals, eight assists) over 38 games during his junior season at Boston University and served as an alternate captain while helping the Terriers to the Frozen Four and title game. Kaplan also added three assists in the NCAA tournament, including one in the national championship loss. Kaplan plays with a physical, power-forward style. He’s strong along the boards and intelligent with the puck. Kaplan signed a three-year entry-level deal and even made his debut with the Flyers late in the season. His blend of size and versatility could set Kaplan up as a potential bottom-six NHL option one day.

Kaplan uses his body as a weapon and is not afraid to mix it up in the corners or in front of the opposition goal. When with the puck, Kaplan takes whatever space is given to him before ripping a shot. Most of his shots come in and around the slot, which should eventually translate to goals.

Coming off his first season at Boston University, Kaplan was one of two Philadelphia Flyers prospects invited to the USA Hockey National Junior Evaluation Camp/World Junior Summer Showcase, which will occur from July 27, 2023, to August 4, 2023, in Plymouth, Michigan. The event is part of the selection process for Team USA before the 2024 IIHF World Junior Championship in Gothenburg, Sweden, from December 26, 2023, through January 5, 2024.

Kaplan was drafted 69th overall by the Flyers.

Devin Kaplan emerged on the scene last year for the US National Team Development Program, tallying 39 points in 46 games with the U17 squad and adding another three points in a two-game audition with the U18 team. Now a full-time member of the U18 team in his draft year, he is among the top-ten scorers on the club through the midway point of the season while mainly playing third-line minutes.
