There are three seasons left on the six-year contract Gostisbehere signed in 2017 at an annual value of $4.25 million. The 27-year-old was limited to 42 games this past campaign due to an injury and frequently being a healthy scratch. He averaged a career-low 18:18 of ice time per game.
Gostisbehere posted 12 points before the pause, then added two assists in five playoff contests before Philadelphia was eliminated in the second round.
There are multiple younger, cheaper options available on the Flyers' roster who can assume Gostisbehere's role on the left side of the blue line. Trading the 2015-16 Calder Trophy runner-up would also free up significant cap space for a squad with only $6.235 million to work with this offseason to potentially add talent, and pay restricted free agents Philippe Myers and Nolan Patrick.
Gostisbehere exploded onto the NHL scene as a 22-year-old rookie with 17 goals and 29 assists in 64 games. He's struggled to consistently match that production since, ranking sixth out of seven Flyers defensemen to play 500 minutes this season with a 46.96% expected goals rate.
