For sure it's been thought of. Nothing new, really, but analytics say just swing for the fences all the got damn time, strikeouts be damned. So I think a whole lot of people have gotten away from some basic hitting tenets. We see it in damn near any MLB game we watch these days. IMHO if you get those big eaters swinging shorter & more direct, more for line drives & fewer strikeouts, they're still gonna hit their share of bombs, or maybe more. I think disciplined, selective guys like Yordan & Paredes already do it a lot, but I could see the benefit of reinforcing that mindset & spreading it around to the rest of the team.
Extreme example: Kinda reminds me of a kid I coached for a few years. Big, strong kid. Catcher. When he was 13, he was a good hitter. Good slug. Good avg, etc. Then we went to Cedar Park and he hit a bomb over one of those tall LF fences. He got fixated on the long ball and started trying to hit more of em. Not only did he not hit another bomb, I literally can't remember him getting solid contact in a game the rest of the year. Seriously, not even once. He was a complete mess. That HR ruined him as a hitter for the rest of that season and most of the next. If he had stayed focused on contact & driving the ball, he'd have hit more of 'em and kept hitting for avg, too.
