I'm in the same boat as @mojo1917 and @BobbyClarkeFan16. I don't think there needs to be a major overhaul.
Moving JVR is a must in my mind. Regardless of the return. It was a stupid move from the 2nd beginning.
Moving Voracek for the right deal would be good also.
Thompson & Grant need to go also obviously.
Remember that having Patrick (who I believe will be back and is a top 6 player) and Lindblom back drastically changes this lineup without losing anybody. Plugging these two in pushes Farabee back to 3rd line where he belongs right now, Laughton to wing and brings in Frost who is ready and should be in the lineup next year.
Giroux - Couturier - Patrick. There was a suggestion about trying Patrick at wing which I think might be a good one.
Lindblom - Hayes - Konecny. Remember this line crushed it for a time before Lindblom went out
Farabee - Frost - NAK. It's a young line but if they click they could really be fast and effective.
Laughton - Pitlick - Raffl. Laughton has proven better on the wing, Pitlick/Raffl are players you need on your cup winning team.
Waiting in the wings: Allison, Laczynski, Ratcliffe, Brink, Rubtsov, O'Brien
Provorov - Niskanen
Sanheim - Myers. This is your 2nd pair for a decade
Ghost - Friedman. Swap any of these with those below as needed.
Hagg
Waiting in the wings: York, Zamula, Morin
That to me is a team that can compete for the cup for several years. Often times I think people forget the Flyers have one of the highest ranked (8 of 31 according to THN) prospect pool, still..... (Thanks Hexy)
