A coach that has roughly 10 years left coaching doesn't care about suicide. They're looking at retirement in 8-10 years. So, they're probably making less than 3-5 mill a year currently, could get a close to $30 million guaranteed to coach there for 2-3 years (2-3 years salary and the buyout when fired) and retire w/ the same amount they would've had for coaching 8-10 more years.
I am 35, and I will do it and commit career suicide for $25 million.
