Gonzaga, the No. 1 mid-major, fell to Illinois this week for its first loss of the season. But with their resume, the Zags are still No. 1 with Creighton, Wichita State and Murray State still slightly behind.
Meanwhile, Eastern Kentucky is still unbeaten. Although the Colonels are yet to face a big test, they have climbed into the top 20.
Read on to see the complete mid-major top 25.
(I consider a mid-major to be any team that does not compete in the ACC, Big Ten, Big 12, Big East, SEC, Pac-12, Atlantic 10, Conference USA or Mountain West.)
