5. 2007 OSU at Georgia: Cowboy teams had been to Tennessee, LSU and Florida, but never had OSU been to SEC territory with a competitive squad. This game didn't stay competitive; the 13th-ranked Bulldogs won 35-14.
6. 1941 OSU at OU: The ancient rivals have staged 103 football games, but only in '41 and '42 were they season openers. The Cowboys had lost six straight to the Sooners, then made it seven with a 19-0 defeat.
