And we also have to take into account ballpark, which ERA+ does. It's not just about what the starting pitcher's average ERA was across the league compared to his because they all pitch in different parks too. So when just comparing ERA across the board, a key component of ERA+ is missed. 'For instance, if the average ERA in the league is 4.00, and the pitcher is pitching in a ballpark that favors hitters, and his ERA is 4.00, then his ERA+ will be over 100. Likewise, if the pitcher is pitching in a ballpark favoring pitchers, then the pitcher's ERA+ will be below 100. As a result, ERA+ can be used to compare pitchers across different run environments. In the above example, the first pitcher may have performed better than the second pitcher, even though his ERA is higher. ERA+ can be used to account for this misleading impression.' It's why I took into account ERA+ and not ERA. And, to be honest, I'm not a big fan of judging pitcher by ERA anyway, but I know many are, so I showed that and also WAR. I was going to break out FIP, you know.
