First off, OTT is not what people think it is. Bryce Molder comes over the top and I don’t think any amateur golfer in the world would not want to play as well as he does. Peter Kostis perpetuated this nonsense and misconception with his comments. Craig Stadler and his son are OTT, Bruce Lietske was OTT…it is not necessarily a bad thing. So if you do something to prevent this on purpose, you are likely taking yourself out of a possible good shot pattern.
The OTT that plagues most amateurs is improper weight shift, no shoulder turn, hands that are too active, a bad release, and most likely, a swing path going back that is too far inside causing the rest of the problems already listed. (not a comprehensive list)
I have said many times that trying to turn the lower body independently of the upper body to initiate the downswing is a terrible idea…and it is.
What you want is the lower body moving toward the target to initiate the downswing and have everything turn together. This will prevent the over the top move (that everyone hates, but doesn’t understand) or hands being too active.
One might say this is a slide. It is not. If your body is turning and the lower body moves toward the target, it is not a slide. It also creates the proper weight shift and stops the “hang back.” As long as you are in balance and your body is turning, it would never be considered something bad.
Even if it is a slide, it beats the alternative. Hanging back and snatching it with your hands.
Some might feel better moving their zipper toward the target. Whatever feel that gets your lower body shifting to the front side while your upper body stays behind the ball (head still) is the feel and movement you want.
The reason I point this out is two fold.
1. Shifting to the front side and not controlling the downswing with your hands is huge.
2. All of the “know it alls” out there want to tell people to stop OTT, get the club in the slot. lag the club, etc., etc., etc., by initiating the downswing by turning the hips and leaving the upper body behind…are trying to screw you up or know as much about golf as I know about women.
