There are a lot of ways to shoot three pointers. You can push it from in front of your head, you can slingshot it from behind your head. You can use your wrists only, or you can use your arms only. Perhaps a combination of both. You can shoot it to the rafters, or on a rope to the basket.
Or you can be Chandler Parsons, and turn your body into a “C” shape as you shoot it. He lands so far in front of the three point line that eventually the refs are just going to start calling them twos. The Mavericks were supposed to be trying to fix this; it doesn’t appear to have worked. Of course, why fix something that isn’t truly broken?
