The Oklahoma Sooners head into Knoxville, Tenn., next week after wiping out Akron 41-3 Saturday.
Meanwhile, Tennessee beat Bowling Green 59-30.
Oklahoma center Ty Darlington told The Tulsa World the biggest jump in improvement has to come between week one and week two, but Tennessee coach Butch Jones thinks the Sooners are already in pretty good shape.
"We know what's coming to Neyland Stadium Saturday," Jones said to Rocky Top News. "I think Oklahoma is one of the most-underrrated teams in the country."
Oklahoma is ranked No. 19 and beat Tennessee last season in Norman, Okla.
