He appears to think that Z is a very good pitcher and sometimes very good pitchers pitch poorly and it has little if anything to do with his temperament. Like he said, his overall numbers are always very good and people still say that, "He'll never be great until" stuff... Me, I've always been kind of meh on Z. I recognize that he's a great pitcher and he's extremely valuable to our team (and for that, I appreciate him), but I'm not personally a huge fan of his because he's pretty much a jerk and his tendency to get wild frustrates me.
