I have read all the opinions of the various posters and while I think King is over stating his reaction to the USGA. Mark my words, their is a battle going on at this very moment between the PGA Tour, PGA of America and the USGA. The PGA Tour is very unsure about banning anchoring, they are a business and their brand is build on Americans, two of which are Keegan Bradley and Webb Simpson. The players board knows this and they are the ones that make the rules for the PGA Tour, not the USGA. The sticky part of this tension is that the PGA Tour doesn't want to be the rules body for golf. They don't want to have a tenuous relationship with the USGA, but they are not going to hurt their brand , by just accepting this latest rules change.
The PGA of America has a different gripe with the USGA. They are the golf professionals all around the country that are going to have to be driving around their member guest tournaments, club matches, invitationals, 2 balls , 4 balls, scrambles etc determining if a player broke the anchoring rule. Was his elbow touching his body? Was the club anchored or just brushing against his shirt? etc. The USGA has proposed a nightmare for club professionals!
Lastly, if there is a power struggle, the PGA Tour will win this battle. Some of you indicated that golfers want the same equipment and idolize the PGA Tour players, that is true and will always be true. If the PGA Tour doesn't adopt the anchoring rule than the rule will not be adopted by golf. I will repeat the PGA Tour and PGA of America are the true movers in the golf industry and they allow the USGA to seem important by letting them handle all the parts of golf that don't generate revenue for the PGA Tour.
