For me, as someone who is both (1) sad that we won't be playing each other every year, and yet (2) happy to see how the new dynamic amongst the members of the new Big 12 has come about, I think it's perfectly o.k. for me to say I'm glad UT is gone but I wish we were still playing. The two thoughts are not mutually-exclusive.
There's no doubt that when Beebe was the commissioner and Dodds was the UT AD, UT threw its weight around and Beebe basically did whatever Dodds demanded. Whether you all agree or not, the perception at least is that UT was the bully in the Big 12 room and there was a constant threat they would take their ball and leave if everyone didn't go along, which they did anyway. It's also pretty apparent there was not a lot of unity in the Big 12 and a whole lot of distrust. Whether that was on UT or not I'm sure is up for debate, but the bottom line is that we've never seen the Big 12 so unified and supportive of each other as we've seen this past year. Would it be that way if OU and UT weren't leaving? Honest question.
So yes, I'm glad UT is leaving the conference because I do think it made the rest of the conference partners better together than what they were, but I'm sad UT is leaving because it means we no longer play each other. I miss the original Big 12 of 1996-2010. But I don't miss the division, distrust, and vitriol that was present between the members...and there was a lot of blame to go around on that one.
