One of these teams will have its College Football Playoff chances essentially erased with a loss, while a win would catapult the victor.
The No. 18 Oklahoma Sooners travel to No. 14 Tennessee on Saturday for a primetime matchup under the lights at Neyland Stadium. According to ESPN's College Football Power Index, the Sooners enter Week 10 with a 19.6% chance of making the CFP, while Tennessee's chances are at 22.6% as the 17th- and 16th-best chances in the country, respectively.
So with almost everything on the line between two familiar head coaches with OU DNA, the spotlight will be on the Sooners and Vols.
