I guess the nature of the loss is in the eye of the beholder.
If you really believed our 2007 team was a legit national title contender, then yes, the Appalachian State loss was terrible. But if afterward, you dialed down your expectations, and realized that team was not as good as advertised, I think the oregon game was worse. Much worse.
Appalachian State was an example of an overconfident team not taking a minor (but still talented) opponent as seriously as they should have.
but Oregon was a brutal loss. we didn't even belong on the same field as them. that feeling of hopelessness was pretty shocking to me.
I don't think I'd felt that hopeless while watching a Michigan game since that Rose Bowl loss to Washington in the early 90's where napoleon kaufman ran wild.
Worst performance? Oregon, hands down.
