One Captious commment on YouTube (not mine!):
I know I'm gonna catch a lot of shit for this. But good golfers know this guy has an advantage over two legged golfers. The only thing he ever had to learn was swing plane. His center stays put because he cannot sway without falling over, and the low point of his swing arch is super consistent cuz he's anchored. This guy is the human equivalent to a belly putter. off the course he is at a disadvantage. But in golf...he kinda has the ideal anatomy.
