You keep bringing up McBeth - you're doing things that look nothing like anything McBeth does. Like I said before - I definitely mis-spoke when I said your hips were out ahead of your shoulders. I think I was wrong saying that they were lagging:
1. You lead with the hips.
2. But your setup is so far off that when you get your foot down it isn't rotated into the correct position.
3. Your hips come through and finish their job.
4. And then, once the hips are completely finished engaging you rip with the arm on its own.
You basically have a breakdown of the kinetic chain. Instead of your hip rotation powering your drive, your hip rotation happens, ends way early, and then you compensate by going all arm into the drive.
I've attached 3 images to show how your hips are completely wrong when you're releasing the discs.
1. A screenshot of you, with your hips a mile behind the action, as the disc is released.
2. A screenshot of McBeth showing his hips in proper position when the disc is released.
3. A screenshot of McBeth's actual protege - showing he wouldn't teach the drive to look anything like yours at release.
In each image I've taken a screenshot at the exact point we can tell the disc is emerging from the hand. In your image - your hips are a country mile behind where McBeth's hips are. When the disc emerges from Paul's hand, and you can see it is by the visible open space between the disc and palm, his pelvis is facing almost completely forward. Likewise with Barela. In your image, by contrast, your ass is almost facing us at the camera behind you.
