There's no such thing as a sure thing, especially in sports. To show what I mean by this, here are a few examples of the worst chokes in sports history.
- Jean Van Velde's epic collapse at the 1999 British Open:
- The New York Yankees losing the 2004 ALCS to their rival Boston Red Sox after being up 3-0:
- Boston Bruins blow the lead in Game 6 of the 2013 Stanley Cup Finals in just under 17 seconds:
- Dallas Cowboys blow a 24-point lead in the third quarter against the Detroit Lions on October 2, 2011.
