And that's without including one last factor -- the one topic that seems to irk Manning when he's asked about it -- his age. Manning is 36, and while there have been age-defying QBs before, there's no guarantee the Giants' QB will be the next Tom Brady in that respect. Based on FootballPerspective.com's average aging curve for quarterbacks, a QB in his age 36 season would be expected to drop .24 in ANY/A. For context, that would make Manning slip two spots in the rankings for that statistic in 2016. Of course, there's no guarantee that he will drop off again, but why shouldn't that be the average expectation?
