Oklahoma's biggest defensive challenge of the season was last weekend at home against Ole Miss. On Saturday, the Sooner defense will face an even bigger challenge, and on the road, at Tennessee.
That's just the way things are week to week in the SEC football wars.
In another weekly marquee SEC matchup, No. 18 Oklahoma (6-2, 2-2) will play at No. 14 Tennessee (6-2, 3-2) on Saturday in a battle of two-loss teams, both fighting for positioning in the upper half of the powerhouse SEC standings. The two losses for both teams have come in conference play: OU to Texas and last weekend to Ole Miss, and Tennessee to Georgia and Alabama.
