Adjusted ERA by season

Adjusted ERA by season
Originally uploaded by zzazazz

Are you familiar with the statistic called "adjusted ERA?" This stat takes the league average as 100 and through a formula determines just how far above or below your ERA is compared to the league average. Here I have compared the season ERA's of Roger Clemens, Greg Maddux and Nolan Ryan. I used these three because Ryan had a productive late career and Maddux has two of the five best all-time adjusted season ERA's (1994-1995) and he is the last person you are going to hear any steroid rumors about and I used Clemens because he spent his morning getting grilled in Washington, DC.
