They don't understand axis tilt. Everything is moving so fast (downswing blackout) that a 2 inch bump is too fine of a movement at that stage. That right shoulder is itching to do something...they are trying to hit it
"straight" so everything moves left.
The worst move I ever saw was a guy that came over the top so much so that he did indeed miss the ball...his club got stuck in the ground then rebounded straight left and hit his ankle...man down...no kidding. I would have helped him up but I was doubled over at the time Same guy...same day... super-toed one that hit a tee marker causing the rest of us to hit the dirt! Company scramble tournaments can be dangerous
How about they don't maintain a flat left wrist, have lost their clubhead lag pressure point and they fail to trace a straight plane line. Just a guess though
