Greg Norman went all in on drug testing in golf over the weekend. He told The Australian that it's really a simple process: "You have to have blood testing, simple as that. It's a pin prick for a player, and you find out what's going on. If you're the head of golf or any sport, if you're the commissioner for a sport, it's your responsibility to make sure your sport is clean. That should be your No 1 priority."
