Justifying the “eliteness” of 2012 rotations using 2011 statistics is probably fallacious from the start. Consider how many players in the above rotations have been effected this offseason by changing teams, changing leagues, dealing with injuries, aging, etc. A team like Texas doesn’t make Berthiaume’s list because they have four pitchers who didn’t spend all of 2011 in a major-league rotation and two pitchers who didn’t spend any of 2011 in a major-league rotation. Does that mean they aren’t “elite”?
Don’t mistake this as a Steve Berthiaume attack. I applaud Berthiaume apparent interest in sabermetrics, as well as his eye for the game. Most hosts are as bland as they are handsome. Berthiaume possesses a genuine curiosity mixed with a healthy skepticism and a willingness to forward interesting and unconventional arguments. But this is the second time in recent memory he’s founded an argument upon a single, highly suspect piece of evidence. That’s punditry, not analysis.
