I am just gonna say it
Foley is a joke! He has small man syndrome. Look at Hunter Mahan! He won two tournaments in the start of 2012 and then he struggled with his swing for the rest of the year. In turn he missed his Ryder Cup Chances because of it.
Yes, as far as I know Foley does teach the 'Stack and Tilt'. Which from what most instructors say is a waste of time and DOES break down VERY QUICKLY!
Tiger had a lot of problems with his swing through 2012. I truly believe that Foley is hurting Tiger and not helping him at all!
