It's ironic how a group here that spends an incredible about of time arguing about the relative merits of the most minute elements of golf course design quickly latches hold of the "they were all playing the same course/greens!" argument when a brown USGA course is at stake. Another stupid argument repeated often on this site over the last few days is "these guys make a lot of money so they have no right to complain," as if the USGA is doing these players some sort of favor by holding the event (Hint: the USGA is a very profitable enterprise). The propaganda machine has been hard at work on your minds!
The point is simple: major championships should be played on courses that are fairly designed and in top condition, to ensure that the winner is determined by skill and mental endurance while, to the greatest extent possible, eliminating luck as a determining factor. Poor green conditions and a silly course setup with wild caroms everywhere seem inconsistent with this goal to many of the game's most decorated professionals, and I agree. Spieth is an incredible young man and golfer, and had a well-earned victory.
As I said yesterday before the start of the round, of course it was an exciting finish - what made it exciting is that the course was so absurd that anything could happen to any player at any time. While the USGA is a business and the ratings were surely strong, making Fox happy, this setup was a major departure from historical standards.
