In your scenario, how in the world does CU recruit well, for, you know, next year's class? A "one year" head coach = worst 2021 class in the P5, and probably competing for worst in all of FBS.Unless EB comes in it Chevs job for a year... keeping him for 1 year at least will keep the class and roster together and can do a full search next year if it all goes horribly wrong.
CU football has been a dumpster fire for 15 years another year of smoldering embers wont make much difference
Recruiting for 2021 doesn't magically start at the of the 2020 season and end on signing day.
