we were literally the first school to make such a choice.
nobody forced our hand. we were the first domino, and it was 100% by our own volition.
what planet do you live on? saying anything else is revisionist history.
All I remember is MO was rattling sabers about how they planned to be welcomed into the Big 10. Colorado, OU and TX were talking about going to the PAC 12. Supposedly the PAC 12 told TX they could keep their network. There was discussion that if OU went, the State of Oklahoma would insist Okie St went wherever OU went. A&M was reportedly talking to the SEC. If all that happened, it would have left NU, KU, KSU, ISU, Tech, and Baylor fending for themselves. That thought scared the hell out of me. Many, many fans and probably some or all of the regents thought something needed to be done right away.
It appears Perlman, Osborne and Delaney did a dance about their and our interest at some convention, but the way I remember it, TO told the Big 10 we were interested and Delaney asked us to "put in our resume" to join. So we were asked.
Unknown whether we checked into SEC. But when our move was announced it was portrayed as us "fitting" in the B1G and we should have joined decades ago. The feeling of people I talked to was our schools were alike (fall leaves, winter, big stadiums, all were AAU schools, etc.). And the non-sports money was way way more than any other conference.
The furthest school at the time was PSU. While WI, MN, NW, IL were not as close to our fans as KU, KSU, CO and MO, they were a lot closer than Alabama, GA and Mississippi.
So as I recall (and I don't think it is revisionist) we urgently wanted the hell out of the B12 before it collapsed, we were asked to join the B1G, it seemed like a fit at the time, the academic associations were coveted by our faculty, and the B1G schools were closer than ACC, SEC and PAC12 schools.
Was it the right choice? Maybe, maybe not, but from my POV, it was the ONLY choice that made sense at the time.
