Some more tidbits:

Kentucky is tied with BYU for the most appearances as a No. 8 seed and has a 3-1 record compared to the Cougars’ 0-4 record.
9 seeds went 4-0 against 8 seeds in the 2019 NCAA tournament and 3-1 in 2018. No. 8 seeds then went 3-1 in 2021 and No. 9 seeds responded with a 3-1 performance in 2022 and 2024.
In 2017, 8 seeds went 3-1 against 9s. Northwestern earned its first NCAA tournament win in school history as an 8 that year.
It is rare for all four 8 seeds to sweep 9 seeds, as it has occurred only three times since 1985, including 2015’s tournament field of North Carolina State, Cincinnati, Oregon and San Diego State.
Villanova won the national championship in 1985 as an 8 seed, and it is still the lowest-seeded school to win it all. But the Wildcats barely beat 9 seed Dayton in the first round that year, prevailing by a score of 51-49.
