A lot has been said about Peyton Manning's offseason neck surgery, but the Colts quarterback says he feels stronger than ever at age 35. Manning is the second-oldest player on his team's roster and he'll begin the 2011 season as the longest-tenured starting quarterback in the NFL. He has yet to miss a start in his 13-year career. Asked on Friday if he was starting to feel old, he quickly replied, "Not really. I've had 20 years of outstanding health, since I was a sophomore in high school. I don't feel that way (old) at all."
