Yeah, I think the message here is different strokes for different folks. While the Cubs methodology for unlocking the best a pitcher can be may work the vast majority of the time, there's guys who just won't take to it. There is no magic bean that makes every guy successful and that's been true forever. Even in the days of the sinker ballers, you saw guys who just couldn't keep the ball down enough to make it work because of the natural path of their arm and pitches. That's why these coaches and development guys get paid a ton of money to figure out what works best for who, and like anything else involving human beings, sometimes they miss something or the message isn't quite delivered the right way to a guy, or maybe he's just not ready to hear that message when it's delivered and 2 years later he is. There's a million permutations and I think looking at the overall body of work where guys like Leiter, Merryweather, Mychal Givens and even Assad and Wesneski, tells you they have a good idea of what they're doing.
