Just listened to the Pawdcast guys and they mentioned that only LSU (22) had more. Checked it and they're right. Minnesota also has 19, but that's it.
Next closest non-P5 is BYU with 16. Next closest G5 is a tie between SMU, Rice, and Western Michigan with 14.
On the other end, some notables: UCONN has 1, Tulsa has 2, Kansas State, Mizzou, and Utah have 3, Tulane and USF have 4, Boise State has 5
