You can see from this photo the shoulder turn is very flat or level which is another good way to describe it. When this happens the players first move on the down swing is to bring the club back to the ball with the club coming down too steeply and often from the outside of the ball which creates either a slice or a pulled shot. The other shot that can often come from too much weight in the heels at address is a shank, because on the down swing you will move the weight to the balls of your feet which will move your body closer to the ball at impact catching the hosel of the club at impact causing the shank. This must be the most unpleasant shot in golf and if you start hitting this shot then please go and get some professional help as soon as possible. I have seen players almost give up the game because of the shanks.
