Yeah this moronic coach-speak, trite, cliche, nonsense is fucking stupid. "Not tolerating mediocrity" isn't an action plan for success nor is it what has made OU so successful. Getting the right coaching hire is a combination of luck, proper research, and timing/circumstances, some of which may beyond any individual's or team's control. Now we've managed to fuck up the proper research bit, our circumstances that we do control we've fucked completely due to terrible athletics leadership from 2009-2018 (jury's still out on CDC), and there's only so much luck can do at that point.
That being said it's important to consider the fact that flukes of history completely change the perception of reality. Imagine how different we'd consider our respective histories of Akers turned one or two one loss seasons into a undefeated season. He was tantalizingly close a bunch of times. If you played each of those losses which were the only loss in the season how many of those losses would turn out to be Longhorn wins in a majority of a hundred trials? What if Big Game Bob pulled his Big Game Bobbiness in his only title?
How many coaches in both team's histories should have been obvious successes but turned into abject failures? Schnellenberger seemed like an obvious success given how he took Miami from an almost canceled program to a title. He resigned in a year. That's an obvious example but if you look through the history of most teams you'll find inexplicable failures and successes.
Shit is fucked, but you completely misunderstand the issues we're facing if you think not "not tolerating mediocrity" is the issue and is what separates OU from us. What causes OU's success is so much more complicated than that and what causes our current failures is also more complex than that.
