I believe Tiger's problem is too much "HOW" and not enough "WHERE".
Nothing Foley is teaching him comes naturally, from the strong grip to the bent over posture to the super shallow move coming into the ball.
It rears it's ugly head on the big stage..........weekends at the majors.
It's leaked into his putting stroke too.
Dump Foley and go back to what his Dad taught him.
If the Foley method was to keep his body from injury, it's not working.
The guy was on his knees after hitting a shot for crying out loud, not to mention the neck, elbow, achilles............
Free the mind and fill it with the simple concepts his Dad and Butch taught.
He needs to give himself a chance to win the 5 majors.
I do believe Butch was good for Tiger and he should have never left him but Tiger is a tinkerer. You can look at it like a college education Tiger has 3 majors in the golf swing. Foley has high talent pros in his stable which have improved their game under his direction. Tiger has said it takes time to adjust to new swing mechanics and so he has proven in recapturing #1 in world rankings, winner of 2013 money title as well as the Vardon Trophy winner. Not shabby I say.
