I think it also depends on what considers reasonable.
Even if you agree on the dollars and years, there's a possibility that the NMC is a sticking point.
Hayes really has no reason to short-change himself with this contract. He knows someone is going to give him the dollars, the years and the movement clause.
In the Rangers case, even if they give him the dollars and the years, there's no reason for Hayes to walk away from a NMC.
He and his representatives aren't stupid, they know he'd still be a trade candidate even with a new contract. They also know the Rangers have some younger centers that could be pushing things in a few years.
So there's no reason for Hayes to leave his future up in the air, when NMCs are going to be on the table. That's just bad business.
The kid is 26 years old and set to become an UFA for the second time in five years. As I've said before, that's not by accident. He's been in control of his destiny and he's not going to trade that element just because he really likes being a Ranger.
