A Risto trade is a hard one to figure out. There have been rumors going back years of Chevy being interested in him and Chevy has been shown to be a GM that will circle back on guys he's targeted in the past. There was quite a bit of scouting happening between the Jets and Flyers last year.
The Jets have been trying for year to get Logan Stanley to play a game similar to the way Risto plays and it just doesn't seem like it's happening so they clearly see a need for that type of a player. Is he decent on the PK?
The problem I see is that even with major retention he's still overpaid and a lot of teams are going to struggle to to fit him in for 2 additional years. Even if PHI holds 50% what does a 3rd pair D even an established one go for? 2nd and a 4th? Or maybe a 2nd and a B prospect or fringe NHLer? At that price is it worth it for PHI to retain that much? If the don't do full retention then what is he worth a 3rd?
I can absolutely see the Jets being very open to something like a 2nd in 26 + Dmitri Rashevsky for Risto at 25%. But for that price if that's truely the best PHI can do are they better off just keeping him. They can always trade him in the last year of his deal and probably get a 3rd or a 4th at that point.
