You get the "Texas always overrated" crowd award. I'm not sure that's a distinction though.
Eh it's more to do with the fact it's a heated rivalry and despite OU being WAY better than Texas the last several years, the Longhorns have made it one hell of a game. including last year's crazy 4OT thriller that OU won 53-45. A few years of past results:
2019: OU 34 - #22 UT 27 (Although unranked, we all knew the Sooners were the better team last year and it wasn't particularly close as the season got rolling)
2018 (Big 12 Championship): #6 OU 39 - #11 UT 27
2018:
#19 UT 48 -v #7 OU 45
2017: #12 OU 29 - UT 24
2016: #20 OU 45 - UT 40
2015:
UT 24 - #10 OU 17
2014: #11 OU 31 - UT 26
2013:
UT 36 - #12 OU 20
All but one of the last 8 matchups is a one possession game. Twice Texas has won as an unranked team against a top-12 Oklahoma team and the other win Oklahoma was #7 in the country. Three other Texas losses were when they were unranked and Oklahoma was ranked, yet still were all decided by5 points apiece. Point is, they obviously play the Sooners as good as anyone in the conference even if they don't always get the W.
