Being a fan of a certain football team from WNY, I totally understand what happened and the reaction.
Coming into the week as a super heavy favorite you ignore the fundamentals, do minimal practice, break curfews, judge a few stripping contests and then show up for the big game with a tiny hangover. You then get hit in the face trying to make a routine tackle and then pin your hopes on a last second prayer from a guy who's never in his life done what you're asking him to do.
So of course you lose.
In the week after, you blame the other team for cheating, the refs for missing obvious calls.
Only when you have some time, you finally admit that you royally screwed up.
