Manning will never, ever be a coach...period. At most he takes a rOle with a NFL team's head office( example: John Elway ). Most likely, he will never work another day in his life. He has made a pretty hefty fortune through salary and endorsements. Look at it this way, had you hit the powerball jackpot would you be back at work? I doubt it. He already has hit his jackpot. To think he would ever in a million years coach here is downright delusional and plain dumb.
He may have to start delivering pizzas if he gets any more Papa Johns franchises.
Probably more likely outcome than becoming our OC.
