Well, you should have expected what everyone with a 12-year-old's understanding of this team expected...basically what we have. This was the first time this year we lost to a worse team. It's disappointing, but it happens. No one, outside of yourself, expected a Rose Bowl this year.
Look around the Big 10. Look around college football. A turnaround from mediocrity to championships takes time. I hate to break it to you, but Tony Dungy isn't on his way here, and neither is Steve Spurrier, Nick Saban, or Coach Jesus. People aren't calling you out because you criticized the team...there are plenty of very fair criticisms to be leveled at the program. People disagree with you because you're overreacting and calling for the coach's head when he is making pretty much exactly the progress most of us expected when he arrived here. Sure, there are issues, but we can't convince the best of the best to come here, so we got the best we could, and he's taken positive steps towards the team you want (a no longer mediocre one.)
Now, instead of a frustrating team that always seems to get crushed by better teams and poop the bed once or twice a year against a worse/equal team, we have a team with the same type of performance, but a ton of hope in the pipeline. This is the first time we've had the talent coming in to actually be one of the better teams in the conference. Dumping this coach for now would be an unmitigated disaster, as we cannot afford to pay for nor attract a higher-tier coach, and would lose much of the recruiting momentum he's built.
