Frost - coming off a bridge deal, Arb-Eligible RFA one year removed from UFA. Don't mind shipping him out if you don't want to give him a UFA deal, seems like he's been on the block forever.
Farabee - 3 more year after this one at $5 million. Turns 25 in a few weeks. Could be a big piece, could be overpaid, possibly even very overpaid. This is probably the key piece to determine how the trade unfolds.
Pelletier - likely a stopgap player who will be cheap and may fit the Torts brand ok
Kuzmenko - just a placeholder to play out the season, will go back to KHL after this season
Mid-2nd round pick - not terrible, Philadelphia has a treasure trove of draft capital for this upcoming draft, which you like to see, and could be gearing up for a tank in the McKenna Draft.
While there's a chance Farbee with his three years left turns out into a big player, which could make this great for the Flames, I think there's the usual thing I see on here of people overreacting the youngness and potential goodness of RFA-aged players. There's a reason once players hit UFA years, unless they're like a star player, they tend to bounce around the league a good bit. The chances of Farbee/Frost ever being part of winning Flyer teams on a realistic, consistent timeline was basically nill and given their contract situations, I wouldn't be shocked if they didn't have much trade value based on contract situations.
