A 15-year-old squares up everything in BP.
Then a tryout coach watches four swings and says, "you're too linear, you need to rotate more." He doesn't make the team.
Here's what nobody told him: that coach wasn't wrong, but he wasn't fully right either and the kid went home and fell into a YouTube rabbit hole where one camp swears rotational hitting is the only real swing, and another swears it turns hitters into pop-up machines.
