Realistically what can we even get for most of these players? This year our expiring UFAs are Kapanen, Vrana, Scandella, Blais, and Sundqvist. None of those are gonna fetch much. Scandella might actually have the most value right now at 50% retained. We would probably be better off re-signing Blais and Sundqvist at league minimum than the paltry value you would get for them. Barring a massive change, Vrana is worthless on the market. Overall you're maybe looking at a third each for Kapanen and Scandella both at 50%.
The two players that we can trade that don't fit our timeline that may actually get value is Saad and Hayes. I wouldn't be in a rush to trade either, as they provide enough value for their contracts, but I could see both getting decent value especially if we were willing to retain for multiple years. Hayes at 1.75M for multiple years would be very valuable for a contending team.
Overall, those four players are really it. Unless you want to trade a core piece like Buchnevich, Parayko, Kyrou, or Binnington, we are not going to add much more draft capital or prospects. I would listen on all of those but I doubt you would get fair value for any of them. Buchnevich makes the most since to trade with him becoming a UFA in a season and a half, but that's tough because he's a player that actually puts in consistent effort, which the culture of this team desperately needs.
