“Down the Line” is one of the biggest misconceptions in golf and Graeme McDowell wouldn’t have won the US Open had he followed that advice.
You could learn a lot from the champion by watching his practice swings. Most would say they looked over top but in reality he was making sure the club goes left after impact or making a circle which according to 9th grade geometry will hit a golf ball dead straight. DON’T swing a golf club inside out! Its a CIRCLE! Most slices oddly enough aren’t slices. Their ball starts right and stays right, thats not a slice. In an attempt to get the ball airborne they swing out and up. Tour players, including Graeme McDowell swing DOWN and LEFT. That’s a little known tour move few are familiar with but, even the beginning golfer who is told they are “over the top” could benefit from.
