Auburn lost to Cal, Arkansas lost to Oklahoma State (0-4 in the Big 12) and Vanderbilt lost to a Sun Belt team. Mississippi State lost to ASU and Toledo. Florida lost to Miami by 24 but beat UCF.
But, the SEC does have some good OOC wins. The actual two best SEC teams - Georgia destroyed Clemson and Texas manhandled Michigan. Tennessee embarrassed North Carolina State, Ole Miss and Alabama won easily at Wake Forest and Wisconsin, respectively....and Missouri beat Boston College by 6 points and Oklahoma had a ho-hum win over Houston.
