Yeah that’s not happening except in fantasyland, the Flyers are rebuilding and have no interest in trades that don’t help the rebuild

A couple issues with this:

Flyers are rebuilding. Not really looking to bring in a player with that much salary. Although they are starving for high end talent and the price isn’t that high. However if it was a high end player that was any other position than RW it would be much more enticing. They have way too many RWs on the roster and coming up through the system.
Marners NMC kicks in soon. If he doesn’t like Torts or or Philly then he could wait it out and leave in FA if he wanted to and we get nothing except him helping us win meaningless games and prolonging the rebuild.

Ultimately not the right move for a franchise that wants to build something sustainable
