I am suggesting the possibility that the time he took to develop a new pitch caused the refinement of his existing arsenal to suffer. Is that hard to follow? How do you do on standardized tests? Am I right? I don't know, but I didn't think he needed to develop a changeup when he was just starting to dominate league batters. If the league had already adjusted to his stuff and the new changeup hasn't kept him ahead of those batting adjustments, then maybe he is just an average pitcher. IMO, he needs to go back to throwing strikes like he did last year. Batters haven't stopped swinging at his borderline pitches. Last year, he got lots of called third strikes. In the Yankee game that he lost in September (despite having pitched beautifully), it's my recollection that most of his k's were looking.
