I'd like to paint a picture for all of you Gruders out there. 1)The guy's an NFL coach. In the NFL, you don't have to go on recruiting trips and kiss the read ends of 18-year-olds, you don't have to put up with athletic directors, college presidents, etc. You tell your players what's expected and, if they don't perform, you fire them. Plain and simple.
2) The guy makes 3.5 million per year doing Monday night football. He can sit in a chair and talk about the game going on and second guess everything that the coaches do, without consequences.
Now, would you, if you had his job and were 50, drop down to the college ranks and basically start a career making the same money, doing 10 times the work, having to put up with college crap (see 1 above)?!
John Gruden will never be a college football coach and I doubt that he'll ever be a pro coach.
