In martial arts that stance is called a soft bow. It gives you the potential for pulling backwards. You do it unconsciously when you pull a heavy door.
This is a very difficult movement, but I disagree with your offarm. Paul’s and anyone’s offarm that starts out wide requires better timing to get it in then down, but I’ll talk from a curled offarm. Try this drill: go into your reachback, then drop your offarm. Notice how doing this tightens the upper back muscles and in turn pulls the driving arm forward and into the box. You can further exaggerate this using a swimming type motion, which drives the offarm shoulder forward such as how Paul’s shoulder is forward, and further tightens the upper back, driving the lead arm faster forward for timing reasons. This is how I’ve been taught by pros to pull the driving arm with the back, but that can only be done using the offarm. I know you teach to curl the driving arm in at the elbow, but using the back via the offarm uses bigger muscle groups while keeping that driving arm loose.
Depends where the basket is. Often on a shot like this you are throwing at an odd angle relative to the basket's position, so your lie is not not 'behind' your marker relative to where you are throwing. Looking at it from the point of view of the throw can make a legal stance look like a foot fault, while a stance that looks legal at first glance might actually be a fault. What matters is that you have a point of contact in your lie, which is on the line of play (line from the basket to your marker), and that all other points of contact are at least as far away from the basket as the front of your lie. This can get pretty weird when the basket is far away / out of sight and well off the intended line of a throw.
Your content is too good to use a pro player in your video. It’s called clic bait. And if you don’t change it I’m not watching anymore of your videos, unsubscribed
I actually like this new collection of videos. I don't look at it as pirating or even click bait. I see it as gleaning useful things from slow motion video of the people that do it best. You begin to realize that there are fundamentals that are the same, but styles vary quite a bit. I think it allows players to find not only what the pros are doing, but what works for us as individuals within the variance of sound fundamentals. I messed up my shoulder following RU-vid advice (pull through lawn mower, etc.). Even the pros can't always relate what they are actually doing and especially, modify for differing body types, age and/or physical conditioning. Wish there were channels like this (and a few others) back when I first started. Great job!
I don't know what the funniest part of this is: that (a) one should only learn from videos of players who are not pros, or (b) one should only positions videos in such a way that people are not motivated to watch them, or (c) it makes sense to walk away from content that is "too good" because of one choice with which you disagree, or (d) announcing this via ultimatum is a totally normal way to go about it. A strange masterpiece of a comment.
