I don't think there are too many arguments about whether rotation occurs in the swing. People (correctly) argue that rotation is not the goal of the swing, or is not the primary power engine.
If you already kind of get it, then I can see how that whole discussion is a little bit odd sounding. If you do NOT get it, and try to mimic what good throwers appear to be doing, it is very easy to go down the wrong path. Some pros even describe their own swing as forcing a rotation (Gibson and the whole spin my belt buckle thing).
The lateral shift being the main power source is something that people can get fundamentally wrong so some people have spent time really hashing out why that is not the right idea.
You can see this with new players trying to mimic those who can swing.
They are trying to rotate weird and flick the disk with their wrist a weird way and it just looks like a cow that put high heels on and is falling all over the place.
The body needs directions to understand things in the simple way. And.. most actions out there are fairly easy to mimic, but.. yeah. Disc golf, no. It's practical when you understand it, but. impractical if you dont have enough knowledge.
And it's a really unique motion in a way as well, because we are trying to drive linear motion into rotational motion, then resist the rotational motion turning it back into linear motion to drive it into leverage.
That's how it works in my brain.
Cause were trying to transfer energy from the ground into our arm to resist against it in a way that it drives the power up into a rotation again that has resistance and.
It's really simple when you think about it.
But really complicated in practice.
And, like.. Brychanus is the only one who seems to have enough discipline to go in the basement and essentially do build up drills.
I was thinking about it... last night or this morning. Maybe while I was sleeping, I duno.
Like I really wanna build my swing out proper by breaking it down and building it up.
The problem is I'm trying to develop my own way of teaching it as well that makes it easy for me to understand and provide drills that make sense to people I can quickly teach in lessons, or put up video clips that help people get there.
So, I could spent 500 reps on something and then try and build it into the next part, and it's just not bringing the results I need. Now I gotta do 2000 reps to build a new one and wipe out the old one.
Which ... if you listen to me complain, I talk about people not putting in the time. And.. I'm not necessarily wrong, but I don't practice it either. because it's hard to spend a week on 1 or 2 things to try and gain a practical understanding. I'm not necessarily trying to do it to build muscle memory. its very frustrating. Especially with my broken body.
