tom, you made this point earlier in this thread and i've been thinking about it for the past few days. I disagree. 2000 was pre-technology, or at least at the dawn of technology. Urethane balls had yet to be fully accepted, launch monitors were nascent (i.e. not everybody was usng them) and thin faced drivers had yet to overcome the world. Tiger (and tiger alone) was at that time a lot farther ahead of the world generally.
in the past two years, others have caught up, due in part to technology and conditioning, in part to working harder knowing they would have to do so to win. Theres a whole group of people who are 15-20 yards longer, and who have been spending a lot of time around the green.
since driver provides so little advantage in so many holes, if somebody separates himself at merion today, i think its because he gets hot for a week with the putter and wedge, and that sounds more like the bob hope than the us open
