Mazzone was .. is .. a craftsman. On the other hand, Wales hit it ... period. PC's are there for most... not all... clubs to catch whatever crap comes down stream. I did.
Pitchers at the professional level are as dumb as a fence post (most of them anyway) single minded egos, me-myself-and-I mentality that's a matter of survival --- cultivated by the business . If they don't cultivate that outlook, they're fair game for all kinds of crap. Pro ball is a dog-eat-dog business, watch your back, get it while you can. Try and manage, no, survive under that big top.
Now enter a pitching coach who is suppose to manage, monitor and all the stuff that goes along with that. Impossible. A stretch of reasonability that just doesn't fly. On the flip side of all this is the ego of the PC himself who constantly has to prove his existence and worth. Again, a stretch.
Mazzone should be grateful for the departure. I would. The man is gifted beyond being appreciated. So, I suggest to Mazzone - kick back, sip a Singapore Sling, and watch the dogs chew on each other. Might even pay to be an odds maker in Vegas? Enjoy the time you have left Leo, you got it coming to my friend.
