What do you think about this breakdown of Avery's hit/disc pivot/wrist action? The disc he is throwing is perfect for seeing rotation as it has a nice black stripe on it. When he has the disc at his right pec the stripe is parallel to his forearm, just before the disc leaves his hand it has already pivoted nearly 90° and with only minimal opening of the wrist. I don't know if it is relevant to notice or mention, but I found it very interesting that his wrist is close to neutral when the disc is in contact with what looks like only his thumb/index pinch at the end.
Some don't know that for best axing power one of the hands needs to slide from the bottom of the handle up the shaft on the downstroke. That helps to "snap" the head around in an arc. Or part of a spiral however you want to phrase it.
It's pretty easy to see. Often their foot/ground speed is slow, and the arm speed entering the power pocket is fairly low, but the disc comes screaming out and, like you say, the motion is very explosive.
The concepts of two stage shoulder rotation, bringing the outer edge of the disc around at the last second, and driving through the point of contact are very helpful...

JR wrote:The reason why the sharpied black bar on the disc moves from parallel to the forearm in the first pic to 190 degrees clockwise in the final picture with only an inch of wrist extension to the right of neutral is the elbow chop arc plus the wrist arc plus the arc of the disc pivoting on top of those arcs. If you drew a picture of the arc of the shoulder, elbow, wrist and the center plus outside edge of the disc you would see many arcs that leapfrog on top of the previous arc.
I think something I haven't seen discussed a lot is the timing and coincidence of all of these arcs and how critical it is. I would love to see a diagram of the arcs as they move through the throw. I'm just loving reading about the hit and breaking down hi-speed video of pro's throwing, I feel like I am learning so much.
Right, the dual stage shoulder rotation is obviously the key. The natural tendency is to increase the speed of footwork and twist your spine super hard and fast with the core muscles in an attempt to generate more power. The dual stage rotation takes a whole shitload of stress off the back, and reduces the need for athleticism, because the first stage is just a nudge, and then all the power is generated by taking advantage of the arm levers and weight shift instead of fast footwork, and spine twist/core muscle.
