With the expansion draft and free agency starting later this month, this would be my GM take on what the Flyers should do.
As far as the Expansion Draft on Jul.21 the Flyers can protect 7 forwards, 3 defensemen and 1 goalie. Several of the young players like Farabee, Frost, York, etc... are not eligible to be drafted while Giroux and Hayes have no movement clauses and also can't be taken. Only 1 Flyer will be taken as the Kraken can only pick one player from every team (Except Vegas). I would protect the following:
Forwards - Giroux, Hayes, Konecny, Couturier, Lindblom, Laughton, Patrick
Defense - Provorov, Myers, Sanheim
Goalie - Hart
That would notably leave Voracek, JVR, Ghost, and Sandstrom available to be drafted
Depending on who is taken, I would then consider buying out either Voracek or JVR if they are still on the roster.
Free Agency begins on Jul 28 The Flyers have a glaring need for a top defenseman, so I would go hard after Doug Hamilton who would pair nicely with Provorov. I would sign Jonathan Bernier to be the back up goalie, and sign Nick Bonino as a depth center.
I don't think a trade for Jack Eichel is likely, unless they would be willing to take a salary back. For example, to make sure salary would work, something like a package of Konecny, Ghost, Zamukla and picks might not get it done. Unlike the NBA salary does not have to match to make trades, I'm just not sure the Flyers have the ammo, unless they move someone like York and Frost.
