Both defenses are not getting enough respect here especially with each minus its starting quarterback. 

Clemson surrenders just 20.1 points a game. The Tigers ranked 10th in run defense. Georgia might be the best defensive team in the country. But Clemson was close to the Bulldogs giving up 4.97 yards per play compared to Georgia's 4.88. 

The Tigers get to face a Tennessee squad that has lost much of its feared passing attack. The Volunteers lost their stud QB Hendon Hooker to a season-ending injury two games ago. The Vols also will be without their top wide receiver, Jalin Hyatt, and third-best wideout, Cedric Tillman. Both opted out of the game to prepare for the NFL draft. Joe Milton replaces Hooker - and it's a monster drop-off. 

Tennessee gave up 27 points or fewer in nine games. The Vols held opponents to 23.5 points on the season while ranking 18th in run defense. 
Clemson won't have its starting QB, DJ Uiagalelei, either. He's entered the transfer portal. 

Because of using largely untested backup quarterbacks, both teams will emphasize the run more, which will eat clock. Each team has strong run defenses, too.
