#1 thing killing the Flyers is the center ice position, especially with Couturier out.
This is a direct result of the complete busting of four first-round centers: Nolan Patrick, German Rubtsov, Jay O'Brien, and Morgan Frost.
Relatedly, the #2 thing killing the Flyers is major injuries: Couturier, Atkinson, Ellis, and, with the concomitant lack of scoring depth, JVR on top of it.
I'm not seeing how it's fixable this season.
Prospects like York, Foerster, Desnoyers, Brink, Gauthier aren't quite ready.
Older prospects who were drafted for wing offense, like, Ratcliffe and Laberge at 35 and 36 overall, are also complete busts, so they are forced to take Hail Marys on other scoring busts like Bellows.
All they can really do this season is try to steal some games with goaltending and when other teams don't show up, and figure out which players to weed out from their plans going forward.
