You need to take a statistics course. It is completely possible for teams at the top of a conference to be worse, while the teams at the bottom have improved. They are not mutually exclusive.
I know they're not mutually exclusive. That's why I phrased the question to include the word "substantial" (in fact, I underlined it actually). It was a reasonable question. Do you think it was equal?
Is Iowa State substantially better than the RP days? They're going to win one or two games this season. Is WVU substantially better than those A&M/Nebraska teams you listed? I honestly don't know and that's my point. The difference is difficult to tell at the bottom because there's a billion variables. So looking at the records for the bottom half of the conference doesn't tell the whole story.
As for the "shifted paradigm at Kansas State," what a load of crap. You guys are 2-4 (0-3) right now. K-State still faces most of the same challenges that they always have. Snyder has been able to overcome those challenges for the most part and build a legacy, but it's very difficult to continue to sustain success at a program like K-State. Perhaps this is a moment where you reflect on just how much built-in bias and delusion you have established when it comes to K-State football.
You really think it's a load of crap that K-State doesn't and won't face the same institutional challenges it did in the pre-Snyder era?
Let's glance at the Futility U article:
The "it's impossible to win at k-state" stigma has vanished.
The "tradition" talking point is gone.
The "fan interest" talking point is gone.
The "money" talking point is gone. (stan parish made 90k a year)
Literally, the only still-applicable portion of the SI article is the following, which the author admits, was pretty weak even back in 1989:
Location. Manhattan, which fancies itself The Little Apple, is located somewhere to the west of Topeka and north of Wichita. Wildcat quarterback Paul Watson says players from outside the state think of Kansas as "flat and nothing." Players from inside the state are mostly hoping to leave. In truth, Manhattan is a wonderful little town in which cars still angle-park on Poyntz Ave., the main thoroughfare. And, yes, they have electricity and talking movies. In fact, for charm and personality, Manhattan has it all over places like State College, Stillwater, Columbia, Tuscaloosa, and South Bend. Says former coach Gibson, "The one thing Kansas has got is great people, but it's hard to sell people."
So yeah, unless one day in the future K-State and its fans suddenly decide that having a respectable football program isn't fun anymore, K-State's not going to have to face the same challenges they faced pre-Snyder. The paradigm has shifted in the last 25 years. K-State cares about football and for as long as college football is a thing, K-State will continue to care about it.
