One thing I will say about Tennessee in regards to OOC, is that if they schedule a mid-major, it's usually a 2:1 or 3:1 contract. Sometimes, they schedule 1:1 OOC games, usually if there is a Tennessee connection i.e. Wichita State and Lipscomb this season. We are playing at Wichita State next year, due to Jody Adams & Bridgette Gordon being on staff there, and Jody always joins Nikki Caldwell and Holly on their Cruising for a Cause motorcycle ride for cancer research. We played at Lipscomb due to Izzy needing a home game in Nashville besides Vanderbilt, and their coach was a Student Manager under Pat.
Budgets also come into play. Holly was only allowed a certain number of away OOC games to maintain the yearly travel budget, and since UTC and Lipscomb are a couple hour bus rides away, those are easy to do.
