xFIP doesn't tell the story with Correia. He's gotten brutalized on FBs for three years (14.8, 12.6, and 12 HR/FB% from 10-12, respectively) while pitching in Petco and PNC. That's a stat xFIP normalizes, but with the track record Correia's shown, count me skeptical on the notion it's something out of his control. At least Guthrie has a damn excuse pitching in Coors and Camden.
