I think if he gets a 2 year deal, it will be from a team that isn't expecting to compete or be good next year. Like a San Jose, an Anaheim, Possibly Chicago. They won't have anything to lose by giving him a 2 year deal, as none of those teams could possibly expect to be competing by 2024-2025.
I think if it's a team that expects to be competitive, I don't really see them going more than 1 year.
I could see someone like Lou and the Islanders doing it, if Lou is still the GM. I think the Islanders probably will be bad (not lottery bad, thanks to Sorokin) but if Lou is there he'll try to compete. Maybe he signs Blackwood 2 years with Varlamov's contract up?
