From N2FL's article on Huskermax:
"Frost is 15-25 (.375 win %) as coach of Nebraska. He still doesn't have a signature win. Heck, he still hasn't beaten a team with a pulse. Of his 15 wins, five came against teams from the FCS (2018 Bethune-Cookman, 2021 Fordham), Sun Belt (2019 South Alabama) and MAC (2019 Northern Illinois, 2021 Buffalo). Of his 10 wins against Power Five opponents, only two of those teams (Minnesota, Michigan State) finished with a winning record. Both were 7-6 in 2018. Northwestern, who Nebraska beat October 2, is currently 3-4. The other seven were a combined 25-48 (.342 win %)."
He goes on to say that Scott has to go at least 2-2 that rest of the year to have any chance to stay for year 5.
My reading of that paragraph and Trev's recent radio program is that only 3-1 and a bowl game would be enough to get Scott to year 5.
By any objective analysis Scott's time in Lincoln has been completely without success, so only by beating three ranked teams and getting to a bowl game this year could he and Trev justify "progress" in the program. Odds of that.........
