For a good chunk of Saturday, the best teams in the Bowl Subdivision escaped with close wins to avoid any major shakeups to the USA TODAY Sports AFCA Coaches Poll.
Then South Carolina scored 35 points in the first half and upset Tennessee 63-38, ending the Volunteers' hopes of reaching the College Football Playoff and bringing change to the top five for the first time in weeks.
This loss losses shake things up just after the top four. Not that this group had it easy: Georgia managed just one touchdown in a 16-6 win against Kentucky, Ohio State didn't put Maryland away until the final minute, Michigan beat Illinois 19-17 on a field goal with nine seconds left and TCU topped Baylor 29-28 with a field goal as time expired.
