It's time to hang it up Peyton.
Some athletes, IMO especially some of the the elite find it next to impossible to give it up. My memory is not up to the task but I do recall several like Franco, Rod Woodson and even Brett Farve refusing to admit that the end was near. Whether it's the big money, the comradery or more likely the lust for the limelight, it still pushes some of these guys way past their safe limits and future well being.
Woodson, 7 seasons after being let go by the Steelers, tied for the league lead in INTs with 8, and finished 2nd in INT return yards and TDs. He also played in his third SB. He retired after the following season.
Ryan who?
Steelers will sign Manning next year, and move Ben to backup.
