While other major sports such as the NFL and NHL are taking steps to address the serious issue of concussions, the PGA Tour has been slow to adopt protective measures and critics have started to take notice. "Of all sports, the PGA Tour should be leading the way," said New York neurologist Michael Aziz, who has done research on the effects of concussions suffered by athletes. "The ball travels faster in the sport of golf than in any other. A golf ball can hit speeds of more than 200 mph off the driver. Yet nothing by the PGA. It's unconscionable." PGA Tour commissioner Tim Finchem insists that the Tour has not taken steps to protect its players because there have never been any concussions suffered during play. "We've only ever had one, but it wasn't really golf-related," he said. "That was when John Daly was drunk and walked into a tree and then fell into a pot bunker. But as long as players avoid getting hit in the face by shots, I think we'll continue to be okay."
