This would be one of the comments that, in my view, helps sway that negative perception. You can't fault fans for supporting the coach and encouraging the team to turn things around. Although I did not agree with a lot of decisions that he made along the way, I supported him up to the Missouri game, and I would dare anyone to call me a sheep. All the defeatist sheep crap does is continue to divide the fanbase further. Same goes with the negavols crap as well. We need to figure out a way to have a genuine discussion without insulting each other.
If you look back on it, you'll see that anytime someone brought up a legitimate point about why it was a bad idea to hire a coach with a losing record, somebody was ready to jump in and insult them and throw out some Vollyanna sunshine crap about how it takes time and how no one else would take this job and blah blah blah. That's not supporting the team or encouraging anyone, that's just poor mouthing defeatist stupidity.
I've lived all over and I've never really seen that kind of "we shouldn't expect to win" mentality from fans of any other major program. That's what is annoying about our fans. If, on the contrary, you're annoyed by fans who expect to win or fans who want the best (as I suspect the OP is), then good luck finding another team to root for, because that's pretty much every major fanbase.
