It's time to face the reality that Roy Halliday is not Roy Halliday anymore and CC Sabathia is not CC Sabathia anymore (and we have to begin to wonder if Justin Verlander is Justin Verlander anymore).
There comes a point, even in great pitcher's careers, when they are not the same pitcher they once were.
They don't have the same stuff, the same speed, the same power, the same accuracy, even the same aura they once did. It can happen gradually, or it can take some time. Sometimes the diminution of dominance is so gradual that we don't see it happening in real time, we can only see it in retrospect.
CC Sabathia: July 16 to July 26, 2011 - three starts
CC Sabathia: July 17 to July 28, 2012 - three starts
CC Sabathia: July 14 to July 26, 2013 - three starts
Since July 14, the league has a 3.16 ERA amongst qualified starters. And, only Josh Johnson's 12.51 ERA is worse than Sabathia's and Joe Saunders' .400 BAA is the only one worse than Sabathia.
How much or how little this tells you depends on how willing you are to accept what your eyes and mind sees and knows.
There are some fans and experts who prefer to see what their memory and their heart tells them.
Now, this is not to say that CC will never pitch another good game. And this is not to say that CC cannot make the adjustment to being more of a finesse pitcher and less of a power pitcher.
It may be just three snapshots over three Julys, but these are three pictures of CC Sabathia and clearly none are the picture of Dorian Gray.
