Bo Pelini's 2 blowout losses against Wisconin (championship & 408); plus Pelini's Prime Time Night game lopsided loss to Russell Wilson Wisconsin 48-17 on ESPN (they were #7 and we were #8); the Pelini blowout loss to #12 Ohio State 63 to whatever... When Pelini got clobbed by Michigan 45-17; And when he got CREAMED by Oklahoma 62-24, etc, etc... Lots and Lots of ugly, embarrassing games there. Not to mention Texas A&M, The Longhorns, Texas Tech, Iowa, Iowa State, Missouri, UCLA Twice, etc, etc... (Thank goodness for Kansas, FCS teams, cream puff non-conference games, KSU, Iowa State, and crappy Colorado, Purdue, Illinois teams at the right time)
Mike Riley - Purdue, Iowa and the 2 games against OSU.
HCSF - The Michigan game was super ugly. That was shocking. Truthfully, there have been 7-11 games this current staff could have won, but the 2nd half got the better of them for whatever reason imaginable.
