I'm not a huge golf guy, but Tiger Woods is the best or second best athlete of all time in my opinion. I might rate Michael Jordan ahead of him right now, but I'm guessing Tiger will be at the top by the time he retires. People that say golf isn't a sport are just plain stupid. I've played pretty much every sport and am good at all of them except golf. It is by far the hardest sport to learn to play. If you have a sports mind and are physically fit hockey, basketball, football, baseball and soccer aren't that hard to get very good at. Golf is just a tougher sport to play in my opinion and he dominates everyone at it.
Also look at it this way. In team sports not only do you have other guys to help you out when you're off your game, but you also are only up against one other team at a time. Tiger wins tournaments against over 100 other golfers, and he won arguably the biggest tournament with a broken fucking leg.
The guy is simply a machine, and if people learned to stop hating greatness you would realize how lucky we are to be able to watch him play.
Also, just watch how low the PGA ratings get now. Not much casual fans will tune in with Tiger not playing.
