Halfway through backswing

Transition to downswing
Rickie Fowler starts with a pretty flat backswing, but comes into impact even flatter. The difference between the backswing is just amazing especially when you consider that most amateurs come into the ball even steeper than they started. I’m not sure how he is able to accomplish this, and although I don’t recommend mimicking the positions I think there is a lot that can be learned from them.
