Match the top-of-backswing angle to the downswing angle
The coach points out that the shaft angle at the very top of the backswing is about the same as the angle of the club in the downswing, so it looks like almost nothing changed from the top into the downswing. He frames this as a simple "one-two" with few variables and says the closer you can get these paths together, the easier your swing is going to be.
