NORMAN, Okla. -- Tennessee Coach Josh Heupel won in his return to Oklahoma -- the same school he quarterbacked to a national championship in 2000 and fired him as offensive coordinator after the 2014 season -- as Nico Iamaleava passed for 194 yards to help the sixth-ranked Volunteers defeat the Sooners 25-15 on Saturday night.

In the 21st century, Oklahoma has faced SEC opponents 14 times with an 8-6 record. However, that record contains some devastating losses in the BCS Championship Game and the College Football Playoff.

Oklahoma has some serious questions to figure out on offense. The No. 15 Sooners were embarrassed 25-15 at home by No. 6 Tennessee in OU’s first SEC game. The Volunteers controlled the game from the start as Oklahoma’s offense was so bad that Jackson Arnold got benched for true freshman Michael Hawkins.
