Actually, they were 6-0, had made a name by beating BIG 10 Maryland, Cincinnati, and Memphis...that's as tough a run as their schedule had. After Riley was crushed by Ohio State and fell to 3-4, Moos was hired the next day to fire and replace him, barring an unexpected and unaided resurgence. Frost at that point, simply because of his Nebraska roots was the #1 target. The administration opened the checkbook, told Moos to "get Frost" if at all possible.
Clearly, Moos is fond of an open checkbook policy and performed the easiest miracle ever by landing Frost to his dream job, with the help of Frost's best friend and an extremely generous compensation package. Of course, Frost had to express how tough it was to leave his undefeated Knights and the perfect weather,..that was, I'm sure, tough to leave for the uncertainly of rebuilding a dynasty back in Lincoln, but when someone offers you your dream job, and gives you more wealth than you can spend, and the associated family security for generations...he was NEVER turning it down for any other job.
