I'd still be surprised to see him go.....
But....a few things....
1 - money isn't really a huge factor....his father passing and leaving him something like 1,600 acres of land, didn't hurt
2 - I believe his wife is still head of the history department at KCD, that's no joke either.
3 - I know his daughter has a great job here, not sure about son
4 - No grandbabies
5 - extended family, not a play right now.
If he goes, I think it's to try and find a way to win another mythical national championship.....that would be huge for his legacy.
