You can't play by just some of the rules. You have to play by all of them, and the rules state that if you have casual water through the green, you must take complete relief.
I knew the decision would produce second-guessing because some people thought the 16th was playable. But if you wanted to take casual-water relief, you could only drop the ball in a position that would put you at a disadvantage to those who had played the hole on Thursday and Friday. You cannot write a local rule that would disregard a rule of golf. That's what some people don't understand.
We considered a lot of things, but nothing outside the Rules of Golf that would compromise the competition. All the suggestions that were made—putting the ball on a tee, eliminating those holes that were unplayable, eliminating the Spyglass scores altogether and playing through the unplayable conditions—compromised the competition.
I know the rule causes problems occasionally, but if you disregard one rule, how can you enforce or administer the others? That might sound extreme, but it's not. The rules need to be followed to the letter.
