Historically especially quarterbacks such as Roger Staubach have gone on to become rich and famous, prospering from their names. I do remember a defensive end, Gino Marchetti of the Colts when they were in Baltimore, getting into restaurants.

I think I have seen Mahones in commercials although I DVR almost everything and zip through commercials, ignoring them as much as possible.
I remember Joe DiMaggio and Marilyn Monroe but I think that was after he retired.
