My college team is in the Big 12 and they are seen on the RSNs dish got rid of.
You may want to check that out. In the Big 12, unlike all other major conferences, teams hold back one football game and a handful of non-conference basketball games (and other content involving less popular sports). Under the most recent deals, all of this content for the "little 8" (Iowa St. TCU, Texas Tech, WVU, Baylor, Oklahoma St. Kansas, and Kansas St.) are now found not on RSNs but on the ESPN+ pay internet service. The Texas content is found on Longhorn Network.
Which leaves Oklahoma. The football game in question for 2019 was South Dakota State, a I-AA team OU defeated 70-14; for 2018 the game was Army, which was a surprisingly close game with OU winning in OT; for 2017 the game was Tulane, from the lowly AAC, which OU won 56-14; 2016 was Louisiana-Monroe from the lowly Sun Belt, 59-17; 2015 was Akron from the even lower MAC, 41-3, etc.
You are talking about one blowout game versus an out-matched opponent. I'm sure there are plenty of bars, cigar lounges, restaurants, and other establishments that will have the game on, certainly if you live in or near Oklahoma.
