re: Mathematically Possible But Unlikely

Typically the 4 seeds are conference champions that typically wouldn’t be considered a top 64 team.
If you were to look at 2023 for instance, the 4 seeds were George Mason, Nicholls, Maine, San Jose St, Tulane, Ball St, Penn, Lipscomb, Central Conn St, Rider, Florida A&M, Army, Eastern Illinois, ORU, Wright St, and Santa Clara.
It isn’t unheard of for a major conference team to make it as a 4, but it’s very rare. I believe ole miss made it as a 4
Edit: ole miss was a 3 in 22’
