I watched all different levels of players this week. From 300’s in the minis to 800’s and everything in between. Side by side. The thing that struck out at me is as the ratings went up, the control of the body increased noticeably. There was less and less wiggle of the stance, ass, torso, head. The stroke went back and forth on the same path. There was no adjustment once down. Etc. the higher the skill, the more these differences stood out.
Sorry not sorry, there is an athleticism gene that separates the field.
