Tell them to Fuck Off, Mike. Do it.
Never happen. Let's be real here. If offered, he will remain the head coach of arguably the most visible sports franchise in the world. At the very least, the most visible NFL team. It's a win/win. If he gets them over the hump, he's forever revered. If not, he still stands to make millions, in a place he's already established.
As fans it's easy to say "Fuck Jerry. I'd never do it. I'd just get another job somewhere else." Well, it's not that easy. Who is offering this job? The perennial loser Chicago Bears? Maybe that powerhouse Browns team? That NY Jets job sounds like a dream landing spot. The London Jaguars? Point being, not only is Dallas the better job, they are a hell of a lot closer to competing than the above mentioned, and probably any other team that would be looking to hire him.
It's not like Fat Mike has a lot of coaching years left in him. He's not looking for a 5 year rebuild. And certainly not one where the ownership/front office is just as toxic as Dallas' is thought to be.
