Necas would become a UFA after the 25-26 season should he go that route.
At this point, barring a trade, I think the best path forward for both sides is a 1 year contract, be it at whatever the arbitration award is or something in between Necas' ask and the Canes offer. That get's Necas 1 year closer to UFA status and gives him one more shot to get back to the 70+ points Necas. He is going to see increased opportunity for the Canes this coming season out of necessity. If that increased opportunity isn't enough for him to produce, then we just go through this rodeo again next offseason. If he breaks out this season, MAYBE both sides become willing to sign a longer term extension. Or maybe it makes the Canes ask for a trade easier to find.
Anyhow, he's what, like $5-$6 million in arbitration? It will be interesting to see the number his agent files.
