Thanks in large part to upset wins by 11-seed Dayton and 7-seed UConn, just 20,890 of the 11 million-plus Tournament Challenge brackets (0.19 percent) got all of Saturday's games correct.
None of the 35 brackets that had just one loss in the Round of 64 went perfect on Saturday, although three went 7-of-8. However, 14 of the 700 brackets that went 30-2 in the Round of 64 got all eight games right.
The biggest bracketbuster of the day was 11-seed Dayton, which was picked in just 3.9 percent of brackets to reach the Sweet 16. Meanwhile, the Flyers' victim, 3-seed Syracuse, was picked in 68.9 percent of brackets to reach the Sweet 16, with 11.8 percent picking the Orange to reach the Final Four and 3.6 percent to win it all.
The other surprise Sweet 16 team was 7-seed Connecticut, which was picked to reach the Sweet 16 in just 20.6 percent of brackets, knocking off 2-seed Villanova. While the Wildcats were picked to reach the Sweet 16 in 71.7 percent of brackets, just 9.6 percent had them in the Final Four and 1.2 winning it all.
In all, 1 percent of brackets had both Dayton and UConn advancing to the Sweet 16.
The president went 6-2 on Saturday, missing Dayton and UConn. The Villanova loss knocked out his second Elite Eight team (he lost Duke on Friday). He's got 13 of his Sweet 16 and his entire Final Four still intact. He currently sits in the 92.1 percentile.
Looking ahead to Sunday's games, some teams considered to be longshots to reach the Sweet 16 who could really bust brackets or help others pull away from the field:
Stephen F. Austin: 5.7 percent
Tennessee: 4.9 percent
Gonzaga: 4.5 percent
Stanford: 4.1 percent
Mercer: 1.5 percent
Also notable are the percentages picking 1-seed Wichita State (65.1 percent) to reach the Sweet 16 compared to Sunday's opponent, 8-seed Kentucky (29.3 percent).
