I have been, so let's talk.
Jimmy was great for those 3 years, but that's been his history: 3 and out. He always wears out his welcome.
And I think he's happier blowharding on TV than doing the work of coaching.
Still, Bill has made some real blunders and I would be amenable to someone new.
(In fact, I've been a Cowboy fan longer than you have)
And if Jimmy wears out his welcome, well, he's been gone long enough he can start a new welcome.
