I'm thankful for everything Jim did for us, but this is not the end of the world. It kind of makes sense for him to leave after losing his star QB/WR (maybe Edwards too?). He probably wants to ski 3 months a year in the offseason and Mohawk Mountain has nothing on the Rockies.
The NIL infrastructure will remain with Mora gone. He showed the proof that it can pay off, now it's time to get the guy to bring us to the Big XII.
I didn't realize it until looking it up just now, but Colorado State has been pretty bad for a while. Last year was their only bowl appearance since 2017. I guess the Pac-12 will be a little better than the current Mountain West?
I will say that I hope he stays for the bowl game. It'll feel a little worse if he leaves us high and dry to cap off our best back-to-back seasons in almost 20 years.
