Exactly, he changed his approach. Sometimes pitchers have terrible statistics their first few seasons before figuring it out, that is still weighted in the career ERA. I don't think there is a more useless stat than career era if it isn't weighted towards what the pitcher has done recently.
Greinke: 3.77 Career ERA
Shields: 3.89 Career ERA
Dickey: 3.98 Career ERA
