It's really not that surprising. As good as he seemed last year he got noticeably worse in the 2nd half. Looking at his FIP Splits it paints the picture that he was awesome in May when he came up, and then pretty much average the remainder of the year. I think we're just seeing a bad stretch from a guy who's a decent starter, which is an unfortunate contrast to his overperformance prior to now. True. I don't think he's this bad, but he's definitely nowhere near as good as his inflated reputation from last year suggested.
