The NCAA Tournament brackets have already been busted for millions of college basketball fans. High Point's upset of Wisconsin played a major factor in ending the hopes of a perfect bracket for more than 25 million who entered ESPN's perfect bracket challenge. The network reported that just under 900,000 perfect brackets remained after the first wave of games. The results were nearly identical for those who entered the challenge at NCAA.com, with more than 96% of the bracket entries already eliminated. The odds of correctly picking every game during the three-week tournament can rise to as much as one in 9.2 quintillion.
