It's the deception that causes it.
This is the big problem with taking data and analyzing it without understanding circumstance. You have a pitch that's effective, but his ability to control it at high velocity and good movement is not as effective as you would assume based on the Pitch f/x numbers, which are through the roof compared to what he's bringing. I'm not saying it's a bad thing, but it's not as good as the numbers indicate. And long-term it's not sustainable production...or at least it's usually not sustainable. Calling it a plus pitch isn't really true to what that actually means.
