Peyton Manning vs. Cam Newton: Can the Sheriff outduel Superman?
SAN FRANCISCO -- We've seen a story like this before. There's an aging quarterback in a Broncos uniform who potentially could finish his career on top by winning what could be his final game, a Super Bowl. Yes, Peyton Manning -- who, at age 39, will be the oldest starting quarterback in Super Bowl history when he takes the field for Super Bowl 50 at Levi's Stadium in Santa Clara, Calif., against the Carolina Panthers -- likely is trying to do just that. Manning won't confirm that Sunday will be his last game. But it sure feels that way.
