ORLANDO, Fla. -- Tiger Woods is taking his role on the recently formed U.S. Ryder Cup task force seriously. He just doesn't want to make it a lifetime appointment. He would judge such a development a failure. "We can only do this once," Woods said Tuesday at the Hero World Challenge at Isleworth Golf & Country Club, where he is set to play competitively for the first time since August. "If we do our job correctly, we're only going to have this once." Woods missed the Ryder Cup because of a back injury, but in the wake of the latest loss by the U.S. team, a 16 1/2 to 11 1/2 thumping in September in Gleneagles, Scotland, he's willing to shoulder some of the burden to formulate a plan to change America's fortunes.
