I want more myelin... Sean Foley Wall Street Journal Article: "Eclectic Golf Whisperer"

Yea Foley is good with those terms and he throws them out like leafs.
He is good building confidence for the player but the golf swing?
Pretty much not understanding it.

Foley doesn't give straightforward answers, though. He is among the most technical and scientifically oriented coaches in golf. He's never without a high-speed video camera slung in a bag from his shoulder and throws around phrases like "correct the thoracic tilt" and "a function of attack angle versus loft in the horizontal vectors." But that doesn't mean he thinks or coaches in anything close to a linear fashion. It turns out Foley, 38, is a seriously cosmic dude.

When I asked him to explain Rose's rise over three years from 67th to 19th to fifth in one measure of long-iron excellence. Foley gave me a one-word answer: "Myelin."

Excuse me? "That's the insulation that wraps around neural brain circuits and helps them fire faster when presented with certain stimuli," he said. Laying down more myelin, over time, helps secure new skills; that's the value of those reps Woods always talks about. " 'Swing change' is really a stupid term, because it's actually just gradual evolution in encoded brain patterns," Foley said.

Rose had terrible back problems for years, resulting from the way he had been taught to swing, so addressing that was Foley's first order of business. "The pain response is omnipotent. It can change everything else in a swing without a player knowing it," Foley said. As much progress as the two have made since then, the "final frontier," as Rose calls it, still relates to that postimpact pelvic turn. He's been working intensively with trainers to improve the external rotation of his left hip. But until that improves sufficiently, Foley said, "it's not worth working on." A good point for amateurs: Foley teaches only what he knows his players are functionally able to do.

For a coach with perfectionist players like Woods and Hunter Mahan, Foley has a surprisingly complacent attitude toward perfection. "Maybe once a year, if that often, you have one of those impeccable rounds, where everything just collides in this beautiful symphony. But you can't base anything on that. Those rounds aren't even very helpful, because we only learn by failure," he said. "Humans are fragile. Mistakes are guaranteed. Our concentration is always shifting. There's no reason, except that this is the natural constitution of the mind."

What's wrong with the video? Well, Sean is mistaken if he thinks that golfers started slicing the ball during the previous generation only.
