I think Tiger still has a couple more multiple-major years in him. It will be interesting to see how he responds to losing a 4th round lead in a major for the first time. He could easily be on the downside of his career. But, it also wouldn't surprise me if he gets pissed and does something crazy like pulling off the Grand Slam next year. Who knows with that guy?
Although, it's going to take a lot for him to legitimately pass Jack as the greatest major golf tournament of all time. Nobody ever seems to bring this up, but in addition to Jack's 18 titles, he finished second <span style="font-weight: bold;">19</span> times and 3rd 9 times. Incredible.
