That was awesome to see, but man what terrible shot selection... but made them!
After a while, when a guy repeatedly seems to be jacking up "bad" shots but is making them at a 40% clip, they stop being bad shots.
A lot of what makes a good shooter in the NBA is having the athleticism to get your shot off at a frenetic pace, with your body not quite in the right position, drifting to one side, hand in the face, etc. Edwards is that kind of shooter. The fact that he's able to get these shots off and make them at a high percentage, from weird angles, from various depths, bodes very well for his future as an NBA player.
Let's not put him in the HOF yet, but... wow.
