I agree with Marty.
Not only do these guys have to go to work in a place they are both disliked, they are under a tremendous amount of stress after failing this year, may possibly be relying on a rookie QB to save their jobs, and get to walk through a place where they watched a guy die every day.
One of them is 65 years old. The other can walk away loaded down with Hunt money.
Why would they stay?
The burden is heavy at this point. They need not carry it. No one will praise them for it.
