I think he'll still be here in 5 years.
What else is he going to do? He's not interested in broadcasting. By his own admission, he has no hobbies and he said during COVID that the time off really showed him he didn't have any interest in just sitting at home doing odd jobs.
I think having the albatross that was Brian hanging around his neck has alleviated alot of the pressure (granted, pressure that he caused, but he was never going to fire his kid himself) and if we can find a way to make the playoff this year, I definitely think he'll keep running it back.
I wouldn't be surprised that, if we do happen to make the playoffs, Beth gives him an extension to probably 2032 after the season.
