As an aside, nothing beats the comedy of people who believed John Wefald and thought the Big 8 was going to kick K-State out and try to bring in somebody like Arkansas. If there's one thing NU and OU wanted and that's more competition.
The truth is in the middle. There was an informal “vote” to kick K-State out that was 6-1 with KU voting keep. The vote wasn’t binding and everyone knew ahead how KU was voting. It was just to send a message. The message had some context that the conference landscapes were changing. If we didn’t invest in football & conference affiliations were to change, there would be very little fight among the others to bring us along. I knew this when I was a kid in the mid-90s.
If I were a squawk and knew this I’d hold it over our heads until the end of time.
This is laughable in the context that, for example: KU was the other team in the Toilet Bowl. They sucked as well and they were making no investment in football. Iowa State sucked. Ostate was mediocre and about to hit the skids because Pat Jones was cheating his ass off and got caught.
If such a vote took place, it was by every definition, symbolic, as you said. Hell even CU sucked ass for the majority of the 80’s.
All you had to do was see the look on Tom Osborne’s face when NU was told they had to play OU again in the Orange Bowl. At their core they wanted zero additional competition in the Big 8.
