Joe Gibbs, 67
Gibbs was the head coach of the Redskins from 1981 to '92, bringing Washington its last three Super Bowl titles. Gibbs retired and was lured into other ventures, most notably NASCAR. In 2004, Redskins owner Dan Snyder gave 64-year-old Gibbs a five-year $28.5 million contract to return to the beltway. In four years, the 'Skins made the playoffs twice, before Gibbs retired again.
