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.
