Yep. It's a result of momentum and follow-through.Many pitchers close the shoulders AFTER the release.
Yep. Not preferred. In younger pitchers, this is quite common. They lack the core strength and/or try to muscle-through the pitch.Some start closing the shoulders and release while their shoulders are in motion.
There has been lots of talk of old people lately... Still in my thirties... hope that doesn't put me in that category... lolA lot of old guys focus more on what happens after and what they can see what their eyeballs vs. what actually happens.
I don't think I said I teach 45 (and if I did somewhere, it was figurative)... but you're exactly right in regards to modifying teaching instructions... so that the result is an evolution into a modeled product.While I agree that 45 degrees is what the best use, if you tell a student this they'll overshoot their target and end up more closed then open. If you emphasize that they stay more open, they'll end up at 45 degrees.
It's important to understand that explaining exactly what happens isn't always the best way to teach what happens.
This said, and I'm sure this will raise the hair of someone I'd rather not hear from... Hips and shoulders at 45 is something I don't teach or ever really say to a student. Instead, I just make sure I put them into the correct positions so that something near a stabilized 45 is happening at release.
Another great observation and post SS. I like your thoughts and it's cool that you point this stuff out... it shows you process stuff and think before you speak - and POSITIVELY contribute... just wish that was a universal thing...
Good segue, too! The stride foot angle post is something I have to get moving on...
