Monday's 7am hour of Mac & Cube began with the excitement that Texas & Oklahoma have officially joined the SEC; then, Paul Finebaum, from the SEC Network, tells us what the atmosphere was like in Austin when Texas joined the league, how Oklahoma might be flying under the radar in the SEC, and how big the Texas-Oklahoma rivalry will be in the SEC; later, we get word that there's a contingent of people that now believe that the best rivalry in the SEC is now the Red River Rivalry; and finally, the guys say how wrong that is.    "McElroy & Cubelic In The Morning" airs 7am-10am weekdays on WJOX-94.5!See omnystudio.com/listener for privacy information.
