Jackson Arnold's stock sailed down after he struggled vs. Tennessee. Who else's stock is down and whose is up in this week's OU football stock report?

The Oklahoma Sooners dropped their SEC debut to the Tennessee Volunteers in Josh Heupel's return to Norman on Saturday night.

On 1st-and-10 for the Sooners following the second forced fumble, Arnold threw a pass behind the line of scrimmage. It was scooped up by Volunteer Jakobe Thomas. Eight Dylan Sampson rushes later — yes, eight runs in a row for the Tennessee tailback — and the Volunteers paid off the third Arnold turnover with a touchdown.
