Go read the quotes from the 2008 alabama team before the Sugar Bowl. They said the same stuff, and then got their asses handed to them by Utah in their backyard.
That being said:
Kansas - 33
UNLV - 23
Only instance I remember players on a team actually saying they were disappointed with bowl/opponent was SDSU vs Army. I think SDSU was top 25 and 10-2
They lost...
