In 2016, anchoring putters will be outlawed, and the joint USGA/R&A ruling caused quite a stir when the proposed ban was announced. The ruling bodies contend that anchoring a golf club to the body is not a swinging motion, and thus not allowable under the Rules of Golf. Supporters of belly and long putters rely on arguments like "the game is evolving," "long putters will grow the game," and "they don't provide an advantage."
Because it's a decision that involves $300 putters, three of the last five major winners, and putting guru Dave Pelz, it made noise in the sports world despite the basketball and football seasons being in full swing.
Reactions to the decision have been interesting, to say the least. Several forum threads (here and here) revealed that golfers were against a ban in 2007, but times have changed, and another poll has a majority of responders supporting the ban. Golf writers, on the other hand, seem staunchly against the ban, and many have been quick to criticize the ruling. Professional golfers seem similarly split, so let's take a bit of time to respond to what people have had to say.
