Two-time Masters champion Bernhard Langer says the debate over putting with long clubs is far from over.

Langer has been using a long putter he anchors to his chest for 15 years, and the German remains one of the best on the 50-and-older Champions Tour, winning the money list for the fourth time this year. He was perplexed when the U.S. Golf Association and the Royal & Ancient Golf Club announced a new rule that would ban players from anchoring the club to the body.

"It has been out for that long," Langer said Thursday at the Nedbank Challenge. "If there is anything illegal about it, why did they not stop it right away? If it is that easy with a long putter, a belly putter, why aren't 90 percent of the pros and 100 percent of the amateurs using it?"

Langer suggested there might be a challenge to the rule proposal.
