Seriously? - I think you have an interesting view of why we left the Big 12. I did find two things I believe I kind of agree with you on.
1) I dont think OU saw NE as a rival the way OU see TX as a rival - Texas A&M realized that during there move from the conference. (I also say the same about Texa$/NU. Alot of fans called them a rival, they didnt feel the same.)
2) I find it funny that alot of our fans now talk about how tough the Big 10 is. For year all we did was talk bad about the Big 10 and the quality of play - as soon as we joined the Big 10 was all of a sudden on par with the $EC.
