I'm not gonna keep arguing about this with you because like OP4 said, you're gonna spin it how you want to fit your argument. However, regardless of why Watson was in contention for the British Open, it still doesn't change the fact that it was the rarest of occurances. All the other majors where Jack and those that played with him make the "ceremonial" two day appearances blow your example out of the water and prove that it was an outlier not a norm. If those guys who were so great and the competition is as ****** as you say it is, those greats wouldn't be playing on the Senior Tour if they could still contend in majors regularly.
Also, its not like Watson was running away with the tournament, so therefore, the easy conditions did play into the other player's hands as well. The games of most pros today are taylored towards the power games. That's why the British Open is such a great test every year because guys have to go away from their usual gameplan. The British Open plays great for a guy who has the control/finesse game like Watson, hence the reason he won 5 British Opens. Like I said before, Watson ran into a perfect storm of great weather and a tournament that plays to his strengths. Add the fact that he played great and you have an old timer with an artificial hip contending for a major. As incredible of a feat as it was, its not hard to see how it happened.
