There are several burning questions surrounding the Flyers this offseason, but perhaps none bigger than what the plan is for a third-line center to slot in between Sean Couturier, Nolan Patrick, and Scott Laughton. While Flyers GM Ron Hextall didn’t totally shut the door on bringing back Valtteri Filppula in free agency, there are plenty of red flags to suggest that the team should look anywhere else for help down the middle. Even with Filppula expected to take a large pay cut from the $5 million cap hit as his five-year deal signed with the Lightning back in 2013 expires, his advanced age and declining production shouldn’t warrant much of a look from the Flyers’ brass in free agency at any cost.
