Wow... that's all I can say. Wow...
Should you have expected to win, yes. Should you be ****** when you didn't. I don't know, maybe, depends on your personality. Should you be RATIONALLY ******? No.
I won't get into any of the other stuff that has already been said, but the bottom line is this. If you go into every game where your OTR is higer and expect to win with no game planning, you reap what you sow. Dude, I've been beaten by teams nearly 100 points lower, with NT squads. Almost always there is one or two things I could have done differantly and, almost always, I've just been on the bad side of the RNG. It happens. Nearly every NC team has lost to at least one team that it was a favorite to; some to overwhelming underdogs. It happens.
The problem is that you want to do whatever it is you want and expect no reprocussions when what you want to do isn't appropriate to the situation. I have no problem with you wanting to do your own thing, but when you do and it is wrong, you can't cry out like the sky is falling. Those NC coaches I mentioned did what you don't, look at the games, win or lose, and figure out what works, what gives them the best chance of winning. You don't. You don't take the advice (not attempts to shut you up as you say, but attempts to give you wisdom) and learn from the loss.
Ok, I will repeat one thing. This was not a slam dunk. This wasn't a win "all day, every day". Not even close. The sooner you realize that, the sooner you can get past it and look at the circumstances, the sooner you can make some sort of change to improve your odds. You want explainations, you've been given them. You disregard them, but you've been given them. Move on and learn something from this.
