Peyton Manning is one of the all-time great NFL quarterbacks. But he did not look that way Sunday during the Denver Broncos' 24-13 playoff loss to the Indianapolis Colts and hasn't looked like his usual self in several weeks.
It could be age catching up with the 38-year-old Manning. And likely his health, as there are various reports out there about the severity of the thigh injury that was reported by the Broncos going into Sunday's game.
So after four NFL MVP awards, three Super Bowl appearances and one Lombardi Trophy, is it time for Manning to retire?
