Ok lets say that Dave Bush leaves 30 meat balls down the middle every season. In one season only 10 of those 30 are HRs, in the next season 20 of the 30 are HRs but out of those 15 were solo shots. The 3rd year 20 of the 30 are HRs again but only 1 is a solo shot but 29 are 3 run HRs. He threw 30 meat balls every year and one year he had a great ERA one year he had a decent one and one year he had a terrible one. Each season he threw the same exact number of meat balls. Sure it is a goofy example but that is the reality of pitching, sometimes you throw a bad pitch and the hitter pops it up, sometimes you throw a good pitch and he clobbers it, sometimes you give up a HR and it is 1 RBI, sometimes it is 3. These things don't come anywhere close to evening out each season, if they did you wouldn't see ERA jump around so much season to season like it does. I think Joe Blanton is a good example of this. 2005 - 5.19 K/9, 3.0 BB/9, 4.43 FIP and a 3.53 ERA because of a 75.3% LOB and a .255 BABIP. 2006 - 4.96 K/9, 2.69 BB/9, 4.16 FIP and a 4.82 ERA because of a 68.9% LOB and a .337 BABIP 2007 - 5.48 K/9, 1.57 BB/9, 3.50 FIP and a 3.95 ERA becasue of a 68.9% LOB and a .306 BABIP. How do you look at those seasons and think 2005 was his best and not just lucky, pretty clearly 2007 was his best and most likely 2005 was his worst? If you had to guess on 2008 what would the guess be? 2008 - 4.85 K/9, 2.73 BB/9, 4.38 FIP and a 4.75 ERA because of a 68.9% LOB and a .306 BABIP. I'm not trying to exaggerate here but 100's of studies have been done on this and have shown that ERA is just useless as a predicator of future success over one season of stats. You really cannot tell anything about a pitcher from one year of ERA because the sample size is still too small. As long as you are using it as a measure of judging a pitchers season you are not going to really understand pitching. Take that comment as me being smarmy or conceited whatever but it is the truth. It can tell what happened but it cannot tell why it happened or whether or not it will happen again and that seems to me to be the really important part of judging a pitcher.
