And how do we know that Miller can't consistently outpitch his FIP? He's done it both his 1st two yrs in the league by more than .50 each yr. That's starting to become a trend, rather than an outlier.
Hudson is one of the few players.... I think you mean he's a successful ground ball pitcher. Cause pretty much any successful ground ball pitcher outpitches his FIP consistently. And the fact if the matter is, Miller is extremely talented. There is no reason to suggest he can't consistently outpitch his FIP over his career.
