Grasping at straws again, are we?
The problem with this team is talent, pure and simple. We've seen this with the Penguins, even with a few top talents, Hockey is a team game that requires depth, you need to roll out 4 lines and 6 defensemen, while the third and fourth line don't have to be allstars, they have to be competent, same with your third pair of defensemen - one bad group can lose you games with a quick goal or two for the opposing team.
Flyers had a lack of depth before they lost Couts and MDZ, now it's obvious. The only solution is time, Cousins is a good example, two years he's a marginal AHL player, last night he was one of the best Flyers on the ice. Ghost went from college to ACL to allstar in two years.
There just isn't much that could be done this season, Hextall moved out Grossman, L Schenn and Vinnie, moved in a couple kids, he'll move in 4-5 kids next year and again in 2017-18. There's no magic trade or free agent in the day of tight caps, the trade would cost assets they can't afford to lose (in three years, when the surfeit of draft picks results in an organization surplus that could be a different matter), the big signing would cap strap them again for five years.
All you can do is grin and bear it, the team isn't that far away, add some forwards like Lindblom, Konecny, AK, Leier over the next two years and they'll look better, add the wunderkids on defense and they'll look a lot better (look at the difference Ghost makes, now imagine Provorov and Sanheim out there as well).
