"What I'm concerned about is that golf has a little bit of momentum going right now," Nicklaus, the 18-time major champion, said after he and his wife Barbara hosted the sixth annual Legends Luncheon at Ohio State University, which raised $1.1 million for Nationwide Children's Hospital. "If the guys don't want to participate, then we might not be in the Olympics after this. They vote next year. And if they vote to keep golf in, then that's great, but if not then we lose that momentum with growing the game."
