It's also worth noting there's a lot of RFAs still out there, many of them more high profile than Sandin. Toronto media just loves making Leaf contract disputes out to be a major issue
Barrett Hayton is still unsigned and out there. Arizona could use him, but they could arguably use a high end young LD prospect more since they just added Cooley, McBain, etc. within the last year and their best LD prospect right now is probably Moser, who is Kral-level as a prospect.
We are somewhat the opposite, where we could use a good LD prospect going forward but we have some decent ones (and Rielly as our top guy for the foreseeable future), but we don't have anyone like Hayton as a center prospect and he will be in his prime by the time we need to replace Tavares.
Same age. Hayton has more prestige, so we may need to add a sweetener, but in general I would say both have had similar trajectories thus far (including injuries). Of course he is also a Soo guy too, but that should not matter much.
Maybe Sandin + Abruzzese for Hayton + something small, and then move Kerfoot to a 3rd team for picks? Arizona gets a solid NHL-ready (or almost NHL-ready) center prospect to mitigate the loss of Hayton + Sandin. Moving Kerfoot allows us to re-sign Hayton. Hayton and Jarnkrok split center duties in the bottom 6. We get some picks to use for later. I would then sign Dronov, de Haan, Stone, Stralman, or Subban to for the #7 job (or we can sign them to a PTO and see if a decent guy hits waivers; I would not use Benn or Mete), and maybe we can even sign Sam Steel and try to rehab him on the Marlies (in the spot that Abruzzese originally would have occupied)?
