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.
