Nobody knows Tiger Woods better than his former caddie Steve Williams, who was on the bag for 13 of Woods' major triumphs before the pair split in 2011.
Williams, who once referred to himself as a "slave" while caddying for the former World No. 1, believes Woods' injuries that have left the golfer winless for over two years are because of his training as an athlete rather than a golfer.

"I guess when he looks back, he might question some of the activities that he did, some of the gym work that he might have done that, you know, had all these injuries escalate," Williams told the BBC. "It is very hard to pinpoint how he has got to where he is now but I’d have to say there is a lot merit in [overtraining]."
Claims that Woods' work ethic in the gym was geared toward being more than a golfer were chronicled in his former swing coach, Hank Haney's book "The Big Miss." In the book, Haney cites Corey Carroll, one of Woods' friends, as saying Woods injured his right Achilles tendon doing Olympic-style weightlifting as he returned from reconstructive knee surgery in December 2008.
There are other excerpts in Haney's book that claim Woods trained (and injured himself) with Navy Seals, pushing his limits — a character trait Williams knows Woods still possess but doesn't know if it will help his golf game.
"I don’t doubt he will come back to the winner’s circle. He is a great competitor, he has an incredible work ethic — when he can work hard — and one thing he does know how to do is win," Williams said. "But whether he comes back and wins major championships? That’s going to be a very difficult task."
Woods, 40, is still without a timetable for a return to the PGA as he recovers from two back surgeries since September, but he is getting back in the swing of things and has begun putting and chipping at his home in Jupiter, Fla.
