Don't mean to ruin every one's mood, but I thought I would see what people viewed as the most demoralizing loss in recent years in Cyclone Sports (basketball or football).
In the sense of the word demoralizing, that backalley beatdown we got from OU in 2002 when we were #9 and they were #2....that was PAINFUL.
I picked Kansas in 05. So much optimism after beating Colorado and getting up in that game early. At halftime I couldn't even imagine loosing that game.
But as mentioned above it is hard to pick from so many.
