re: How much more does Manning have left? Is he close to done?

I just think he's an older guy that is coming off of a neck surgery, with an arm that just isn't that great anymore.

It's amazing that he is still playing at such a good level. Just shows how amazing of a quarterback he has been over the course of his career. The best.

He shouldn't quit after this year. However, if he comes back next year and can't play at the level he wants to again, I think he'll hang it up.
