I’ll type slowly so you understand. The ‘yips’ and no nerves are bad things in golf, making winning virtually impossible. By definition a golfer with 16 PGA tour wins (including last years FedEx cup) does not suffer from these maladies. You don’t have to be good at golf to understand that, it only requires being good at logic.
Furyk looks to me to definitely have the "yips" and he has problems closing out tournaments. He had the U.S. Open in hand before shanking one into the woods that barely went 100 yards. Yes, he did win a lot in the past, and he won the Fedex 2 years ago (last year's winner was Bill Haas, not Furyk). All golfers eventually succumb to pressure and the yips, otherwise they'd excel into later age. Vijay Singh was winning a lot into his 40's before the yips got him. A belly putter has not quite cured him of it yet. And remember that Furyk was a captain's pick. He did not do well to qualify on his own. Jack Nicklaus, Nick Faldo and other veterans have commented about how the yips become much more prevalent with age.
