Tom Brady has declared himself available for another 6-7 season at NFL when he revealed his plan to Patriots' owner Robert Kraft. Brady is currently 39 years old and is set to become the oldest quarterback to take part in NFL history if he plays for the amount of time as planned by him.

Brady's form has just been phenomenal even at this age and the player has shown no sign off backing off in terms of intensity and dedication for winning things. Patriots are winning Super Bowls and Brady is contributing ably in those victories. This sparks a thought that there are few more quarterbacks who can play the game until the age of 45.

Aaron Rodgers at the age of 33 is very similar to Tom Brady. He can easily play until the age of 45, that seems a far way off but the way he is playing and his arm strength as good as it gets, to add to it he is one of the fastest quarterbacks in the NFL. With these things pointing in a positive direction, there is very little doubt in Rodgers playing another 10 seasons.

Drew Brees at the age of 38 has been throwing more than 5,000 yards in four of his last six seasons at NFL. He is incredibly effective and his passing percentage is well above average around 70. He leads in league attempts and completions. The Saints can get more out of him if they utilize his running game more. Playing another 7 seasons wouldn't be a problem for, Brees, if he wants to, which means he can till 45 very ably.

Eli Manning at the age of 36 is another ironman in quarterback position for the Giants in NFL. He hasn't missed any game since becoming a starter for the Giants back in 2004. Manning hasn't been injury-prone in his career which clearly means if he continues to be fit, playing another 8-9 years won't be a problem for him.
