According to an upcoming book by his former coach Hank Haney, Woods was extremely close to quitting golf altogether and becoming a Navy SEAL.
An excerpt from Haney's book:
Imagine what could have happened if Woods really quit 8 years ago, and followed his other dream of being in the military. We may have missed out on some of the greatest golf we've ever seen, from 2005-2009, when Woods won 6 of his 14 Majors, and dominated the PGA Tour.
I didn't know how he'd go about it, but when he talked about it, it was clear he had a plan....I thought, Wow, here is Tiger Woods, greatest athlete on the planet, maybe the greatest athlete ever, right in the middle of his prime, basically ready to leave it all behind for a military life.
Tiger did two tandem parachute jumps, engaged in hand-to-hand combat exercises, went on four-mile runs wearing combat boots, and did drills in a wind tunnel. Tiger loved it, but his physical therapist, Keith Kleven, went a little crazy worrying about the further damage Tiger might be doing to his left knee...One morning I was in the kitchen when he came back from a long run around Isleworth, and I noticed he was wearing Army boots. Tiger admitted that he'd worn the heavy shoes before on the same route. 'I beat my best time,' he said.
We may have also missed out on his well-publicized downfall. He might even still be married, who knows?
