I love your optimism, but ISU isn't going to be in the Big12 CCG more years than they aren't. ISU had the exact same team last year and he won 7 games. It takes time to develop guys, when you just aren't rolling out top 20 recruiting classes all the time. Kolar, Purdy, Hall, all the weapons were in Ames in '19, but the OL wasn't there, that is what happens you have have to develop players it takes a Foster 5 years just to be decent for example.
You can keep your head in the sand and think that a 2 year stretch will last 10, but your bubble is going to be burst. It isn't like CMC put out a great team even as fast as KF did, and then KF had an awesome 3 year run, and then the air came out of the bubble, that is what happens. Teams rise all the time in college football for a year or two, but keeping that going is hard as hell.
