Oof. Coaching matters, especially with as many "philosophies" on pitching. Particularly in the transition from high school/travel to the SEC. I remember David Adams used to tell the story about Dewayne Friend going to the mound in the middle of a game and asking him "Do you ever throwing a [effing] fastball with less than [effing] max effort?" With the hyper focus on the gun currently, it's gotten even worse. It seems simple, attack the zone and work fast...but in the SEC it's much more complicated. As a former catcher, it's a given that pitchers can be flaky and the mental side is much more significant once arm talent is established. Butch can't be teaching that every day with everything else he has to deal with, only so much time those guys can be on the field or in the pen. Take a look at the programs that have entrenched themselves at the top of the league and see who has pitching coach turnover. Alan Dunn was at LSU how long...? Arkansas and Vandy likewise.
Gonzo seemed very promising, but something (or someone) got inside his head and that ship sailed long ago.
Again, as a former catcher, I happen to think that receiving has huge implications for a pitcher as well. Current #1 will go a long way with a bat in his hands, but not as a catcher.
