I can confirm through a buddy of mine who works at Utah State that Vigen is not in the mix there. It's looking like a two horse race between Hill and Mendenhall. Hill has some lofty demands for funding and NIL, while Mendenhall requires a steep buyout at UNM given it's only his first year. They're weighing which of those two would cost more.
Fresno State on the other hand is very much in play for Vigen. According to their chat board, it looks like a 4 horse race between Vigen, Eck, Matt Entz, and the interim. The consensus among the fans seems to either be Eck or Entz.
I suspect both jobs will probably be filled this week. If New Mexico opens up, that will be another one worth watching.
