It’s a top 25 job if you make it one.
The big thing that becomes hard to turn down is millions. You get USF to a playoff and you will have offers for 2-3x with buyout probably in the tens of millions. You have to really value things money can’t buy, like location, to stay put.
And it’s not just the salary. It’s the whole budget, the facilities, the belief you’ll have better athletes and therefore it will be even easier to win (“Hey I did it recruiting SEC and Big10 rejects at G5U, so with better athletes I’ll be unstoppable!”).
The only type of coach who isn’t going to jump at more money to a more competitive conference is one who:
1). Isn’t coaching for money.
2). Isn’t coaching for ego and status.
Finding any human whose ambition is not driven by either of those things is going to be difficult. They exist, but they’re probably less than 1% of highly “successful” people because their measure of success is some other value and therefore they don’t find themselves in positions that are associated with high status or high compensation.
