The 20 Best NFL Passing Seasons in the Last 25 Years
5. Peyton Manning, Denver Broncos (2013)
Years removed from his time with the Colts, Manning posted another season of more than 8.03 ANY/A -- this time with the Denver Broncos. In this, his second season with the team, the 37-year-old passed for 5,477 yards and 55 touchdowns.
Manning averaged a league-best 8.87 ANY/A and accumulated a passer rating of 115.1. He won the MVP, but his team came up short in a Super Bowl matchup with the Seattle Seahawks.
