Brackets have closed, we’ve analyzed the millions of picks, and Butler is the world's most popular upset selection from NCAA.com’s Bracket Challenge. Here are the most popular, in descending order:
|Region||Seed||School||Opponent||% to upset in R64|
|West||11||San Diego State||Houston||25.18%|
|Midwest||12||New Mexico State||Clemson||20.27%|
|West||12||South Dakota State||Ohio State||16.41%|
No surprise here: the top three selections are all four 10 vs. 7 matchups, followed by three 11 vs. 6 matchups... and then a 12 vs. 5 matchup!
While 12 vs. 5 matchups are the most talked-about upsets in tournament conversations, the teams are still (theoretically) separated by a larger gulf than the 11 vs. 6 matchup, iwhich goes to show how widespread narratives shape decision-making: fans have decided they like 12-seed New Mexico State’s chances against a 5-seed Clemson team, one that endured a brutal ACC schedule, better than 11-seed St. Bonaventure’s against 6-seed Florida.
The top choice here is Butler, a team whose back-to-back deep tournament runs — and one near-historic title game win — likely remain fresh in the minds of college basketball fans. Less than one percent away from a 50-50 split is pretty impressive for a 10 vs. 7 matchup, even if the 10 vs. 7 matchup is statistically the most even of any double digit-vs.-single digit matchup in the tournament.
Oklahoma follows in second, close behind the Bulldogs thanks in large part to sensational freshman Trae Young.
Only time will tell whether these pan out, but for now, it looks fans are embracing the upsets as always.
