Eli Manning's agent expects the New York Giants to offer him a new contract when his current one expires at the end of this season.
The quarterback has spent his entire career with the Giants and signed a seven-year extension in 2009.
However, that expires next year but his agent, Tom Condon, insists that elite quarterbacks are rarely allowed to hit the open market.
He told the New York Daily News: "The interesting part about it is, since 1993, the inception of free agency, has there ever been an elite quarterback hit the open market?
"Peyton [Manning in 2012], but he had four neck surgeries and no idea if he would ever be well enough to play. Drew Brees, when he went to New Orleans [in 2006], he had 15 studs in his shoulder, in his throwing arm. There's nobody else that's ever come up. They just re-do you."
Manning has won two Super Bowls, in 2007 and 2011.
