Was referring specifically to the idea that if your #4-5 starters are hemorrhaging runs - to the tune of 6+ ERA's - that the next year your run differential would surely be in for a large easy improvement, and in that sense the Y1 run differential would be indirectly misleading.
PythagenMatt isn't limited to that idea, is it?
Lemme re-set here, 'cause am curious: in a situation like 2009, would French's and Olsen's bloated ERA's be "seen through" by PythagenMatt?
