If he can't beat a rebuilding Utah team in Provo, and can't run the table in 9 games against MWC/AAC/FCS competition, then it would be hard to argue that he's better than Bronco.
As for Rose, I have always said his minimum acceptable performance is 1) run a clean program, 2) win 20 games a season, and 3) make at least the NIT.
Other than not getting Nick to clean up his language, he has met my minimum standards this year and should be kept on.
