Good input. My son graduated HS in 2017 and is happily no longer playing baseball and is a junior at the big D1 of his choice (and my Alma Mater). He was the wire-to-wire hit leader of his NoVA HS (not a powerhouse by a longshot) and for doubles as a senior. He always focused on controlling the game defensively, getting the most out of his pitchers, and not letting anything get by him. And hitting gaps. He also ran a 6.95 60. Nobody cared.
If he wanted to and could somehow do it all over again, he should have focused on bat exit velo and pop time. And that's about it.
