Long time no post, but here goes... Frost's buyout, if he was shown the door after this year, is $20 million. Therefore, no matter who the new AD is, the only way Frost isn't back through at least 2022 is if he quits (and that's not happening). If Frost has a non-winning (no bowl) season this year, it's a safe bet that he'll be given an ultimatum for 2022. The buyout after next season would still be very high, but likely more digestable. That said, I believe there are reasons for optimism (7, perhaps 8 wins) this season if Nebraska can get off to a 3-0 start.
But obviously, the problems run deep. Apathy has set into the fan base (season ticket sales and seat donations have dropped considerably) and recruiting has taken a hit (poor on field performance and COVID have taken a toll). If Frost can't get the ship turned around this year, the new AD is going to be in a helluva spot. It's easy to see why sitting athletic directors aren't exactly attracted to this situation.
