Peyton Manning's Broncos are undefeated, but fantasy-wise Peyton is having a historically bad season. Did he finally peak as a quarterback last year? At what age do quarterbacks start to decline?





To find out, this tool shows you when NFL players reach their peak fantasy output by position. It also lets you plot any player's annual performance for comparison. The data cover the last 20 years (1994-2014) and the gray bands represent the performance of the top 30 players in that position. Each band is 10 players, so the light gray band shows the top 10, medium gray is players #11-20, etc.





You can change what position you want to see by selecting it from the dropdown, or just start typing a player's name in the box (try Peyton Manning!)
