There was a time a few years ago when Tiger Woods could win a golf tournament even if he wasn't playing at his best.
Knees would get weak, and golfers would start making mistakes if they saw his name at the top of the leaderboard.
If a golfer had to play in the same group as Tiger, he would make them so nervous that many of their rounds ended in disaster.
That was even when he wasn't playing well that week. If he was on top of his game, he was almost unbeatable.
