There has never been a documented perfect March Madness bracket

In all the years that March Madness - the basketball tournament of the 68 best NCAA teams in the United States - has gone on, there has not been one documented perfect bracket completed. With a total of 68 teams in the tournament, there is a total of 63 games played from start to finish. To get a perfect bracket, you would need to get all 63 of those picks correct. Statisticians have found that even with knowledge of the sport and the teams, you have roughly a 1 in 9.2 quintillion chance of building that perfect bracket.
