Lydia Ko Kicks The Video Habit 

Hubert Green never looked at a video of his swing. He once told a friend that he was afraid he might throw up.

In the 1970s and ’80s, Seve Ballesteros didn’t study moving pictures of his motion. That obsession didn’t come until the late ’90s with the advent of the miniature video camera. Such screenings didn’t serve Seve well. His last win came in 1995 and by 2000 he couldn’t find a fairway with a GPS.

Pick your all-time favorite Hall of Famer – Jones, Sarazen, Hogan, Snead, Watson, Nicklaus, Wright, Whitworth, King. Did any of them spend hours hunched over a video screen studying positions, angles and slow-motion sequences? Of course not. Some teacher with video software surely would have told Byron Nelson that he had to fix that head-dip or insisted that Lee Trevino narrow and square up his stance.

Imagine the heyday one of today’s modern video instructors would have had with Eamon Darcy, Bubba Watson, Jim Furyk, Bob Murphy, Miller Barber, or even John Daly, who can’t get it square from that backswing with that belly.
