Despite a seemingly lackluster slate of games, college football met its craziness quota with upsets and near-upsets involving many of the teams in the middle of the race for the national championship.
One is previously unbeaten Michigan State, which suffered a second defensive meltdown in as many weeks and lost to Purdue.
Also in the Big Ten, Ohio State was pushed to the limit by Nebraska, which slowed the nation's most productive offense but was undone once again by failures on special teams and inside the red zone.
Another is Cincinnati, which is making things more and more difficult for even its most ardent defenders by struggling to put away Tulsa.
