Kris Bryant is a pretty good example. Fowler last year made some significant changes IIRC. Hell, the whole team has drastically reduced it's strikeout rate from one of the highest to one of the lowest...that's not just Heyward and Zobrist. Right, but again, Rizzo seemed to have to COMPLETELY change his approach. I think THAT'S what a lot of us have come to expect or hope for, at least in terms of how "easy" it should be, as opposed to guys tweaking just part of how they approach an AB. Honestly, I'm not really sure if Rizzo's changes are any more drastic than any of those guys and just more publicized specifically. We just know more about the stuff Rizzo did as it's been talked about a lot and the changes are more obvious to the untrained eye.
