I'll (respectfully) agree to disagree with you on this one.
There are indeed those who had doubts and were pessimistic after our last loss. Personally, I think that includes most of the fanbase - myself included. But then there were also those who dug in their heels and argued that one game proved that our head coach was awful, the team was awful, we should do away with the football program, etc, etc.
As you said, we're completely capable of screwing things up again. But those who treat every loss as a "Gotcha! This team sucks!" are the people who really need to check their assumptions, and consider if the data is backing up their overblown claims (especially egregious, if they graduated from GT).
I have no problem with being pessimistic. That's normal - if you have no doubts that we're the best team in the nation, especially after a loss like BG, you're likely not living in reality. But if you have no doubts that we're the worst team in the nation after a loss like BG, you're also not living in reality. Those are the people who should probably check their hyperbolic approach. And I'm fine with calling those out who were 100% certain we were the worst team ever and we should fire our entire staff into the sun.
