Just my two cents:
Saying we are the regular season champions this year is a lot like saying we were the worst team in the Big 12 in the 90s or that we tied for third place in 2018... We don't have a trophy to prove any of those things, but all of those statements are objectively true. The reason we are celebrating that is because we have never been in this position before and many of us never even imagined that it was a possibility.
That being said, I would trade a regular season championship for a Big XII Conference championship, which comes along with broad national recognition and an actual trophy, in a heartbeat. Hence why all the coaches and players are still saying there are bigger goals out there.
Yesterday's game was a great moment in Iowa State history and this season will be looked at as a real standard-setter for the program for decades to come. But how we remember this season will be significantly colored by how we preform in the Big XII championship game and in our New Year's 6 Bowl. That is just as true as the fact that we won the Big XII regular season.
