"Yeah, right until you suck -- I think that's a pretty good rule right there, said Manning.
Manning is entering his 17th NFL season and was named last season's Most Valuable Player after throwing for a league-leading 5,477 yards and 55 touchdowns.
The 38-year-old has had four neck surgeries, including one that caused him to miss the entire 2011 season.
