NCAA Tournament Day 1: Perfect Brackets Plummet Amidst Upsets

The first day of the NCAA Men's Basketball Tournament resulted in a substantial decrease in the number of perfect brackets submitted across various online platforms. Multiple upset victories, including those by lower-seeded teams, contributed to the elimination of tens of millions of perfect bracket entries by the end of the day.

Out of over 36 million brackets submitted across major online platforms, more than 14,000 remained perfect after the initial 16 games. This figure was reported to be lower than the previous year but higher than in some other recent seasons.

The Day's Impact on Perfect Brackets

Early results significantly reduced the pool of perfect brackets with rapid succession. The initial eliminations highlighted how quickly the tournament can shatter the hopes of a flawless bracket.

The victory of No. 9 TCU over No. 8 Ohio State with a score of 66-64 was the first major blow, eliminating 14.5 million perfect brackets. This was quickly followed by No. 4 Nebraska's dominant 76-47 win against No. 13 Troy, which further reduced the pool by 2.5 million perfect brackets.

The first significant upset came when No. 12 High Point secured an 83-82 victory over No. 5 Wisconsin, decreasing the total to approximately 2.3 million perfect brackets. A subsequent win by No. 6 Louisville (83-79) against No. 11 USF further reduced the total to 1.2 million perfect brackets. After victories by No. 1 Duke (71-65 over No. 16 Siena), No. 5 Vanderbilt, No. 4 Arkansas, and No. 3 Michigan State, over 700,000 perfect brackets remained.

Notable Upsets and Dramatic Outcomes

The first day was marked by several captivating upset victories that challenged expectations and significantly impacted bracket perfection. Sources reported between three and four upsets, matching or exceeding the total from the entire first round of the previous season.

Key upsets and game outcomes included:

  • No. 12 High Point 83, No. 5 Wisconsin 82.
  • No. 11 VCU 82, No. 6 North Carolina 78 (overtime). North Carolina played this game without freshman leading scorer Caleb Williams, who was absent due to a broken thumb. The Tar Heels had held a 19-point lead in the second half.
  • No. 11 Texas 79, No. 6 BYU 71. BYU had previously lost player Richie Saunders two months prior due to a torn ACL and entered the tournament with a record of losing five of its last nine games. BYU had faced a 17-point deficit during the game.
  • No. 10 Texas A&M 73, No. 7 Saint Mary's 50. (Note: Source 2 reported the score as 63-50.) Saint Mary's leading scorer, Paulius Murauskas, did not start due to illness and was limited to four points in 23 minutes.
  • No. 9 TCU 66, No. 8 Ohio State 64.
  • No. 9 Saint Louis 102, No. 8 Georgia 77.

Additional games that impacted bracket perfection included No. 3 Gonzaga's 73-64 win over No. 14 Kennesaw State.

The Shrinking Pool: Perfect Brackets at Day's End

By the conclusion of the first day, the number of perfect brackets continued its steep decline with each game. Following VCU's thrilling victory, slightly over 300,000 perfect brackets remained. This total was nearly halved to approximately 150,000 after Texas A&M's decisive win.

Texas's upset victory then reduced the number to just over 30,000 perfect brackets. Finally, after Saint Louis's win, fewer than 15,000 remained. Ultimately, after all 16 games of the first day, just over 14,000 brackets remained perfect, representing approximately 0.039% of all submitted brackets.

For ESPN's bracket challenge, approximately 24,000 of its 26.5 million submitted brackets remained perfect after the first 12 games. The NCAA's official bracket challenge reported similar results, with 0.09% of entries remaining perfect after 12 games.

The Odds of Perfection

The NCAA estimates the probability of completing a perfect tournament bracket, encompassing all 67 games, to be approximately one in 9.2 quintillion when selections are made randomly, or one in 120 billion when making educated selections.

Annually, an estimated 60 to 100 million brackets are completed, with only a portion submitted through online challenges. The swift elimination of tens of millions of perfect brackets on the first day underscores the immense challenge of predicting the NCAA Men's Basketball Tournament.
