It's a young man's game, or so we're told. But that doesn't mean some of the older generation aren't still contributing at a high level. In fact, right now in the league, there are 33 players over 35 who have contributed this year, with 17 of those offensive or defensive starters.
That number increases to 54 (with 29 starters) when you look at the age of 34 or over, which is the guys we're focusing on this week -- those golden oldies still getting the job done in what for most is the twilight of their career.
As ever, position grades aren't necessarily cross comparable, but here are the top five players 34 years of age and older based solely on their performance in 2013.
1. Peyton Manning, QB, Broncos: +26.5
Is there any surprise here? Manning had some issues in November after his fantastic start to the year but rebounded in timely fashion when the Broncos needed him to pull them back from the brink against the Chiefs. The oldest man on the list, he's also our top-ranked quarterback regardless of age and third only to Aaron Rodgers and Philip Rivers with an adjusted accuracy percentage of 77.5 percent. He's not the player he once was, but when you're that good, you can drop off and still be something special.
