If gruden wanted an nfl job , why wouldn't he have taken one by now? There has been quite a few hires since he was fired from Tampa. He's proven he can win in the nfl. He's also been fired not long after winning that Super Bowl. In the nfl he had to rely on highly paid athletes that may not have the same determination that they had as college players or after they get the big money. (Chris Johnson). Coaches are also replaced often in the nfl.
So , if his wife is all tennesse ,(if youre married ,everyone knows who really decides whats best for the family)he supposedly loves it here. Why not come back home. To keep your job in college all you have to do is win. He then possibly has a job as long as he wants it. A chance to coach hungry young guys who want to prove themselves. Momma is happy to be back home. And all of VN rejoices.
