CLEMSON — Clemson football allowed 28 points in the first half against Duke , and Tigers coach Dabo Swinney was not pleased by his unit's performance.
Swinney went over to the defense and spent nearly a minute tearing into them after Clemson allowed Duke to tie the game seconds before halftime. Blue Devils quarterback Darian Mensah earned his fourth passing touchdown after finding wide receiver Que'Sean Brown for a 43-yard touchdown.
The broadcast crew doing the game for ACC Network mentioned they could hear Swinney from the booth.
Clemson (3-4, 2-3 ACC) is tied at 28 with Duke (4-3, 3-1) at halftime on Nov. 1 at Memorial Stadium.
Clemson's defense has had significant breakdowns throughout the Week 10 game, including a wide open 77-yard touchdown. Clemson has allowed 252 yards with 241 of them coming from the air. The Tigers are facing Duke , the No. 4 passing offense in FBS, but Swinney was disappointed with how his team has defended the Blue Devils.
Tiges first-year defense coordinator Tom Allen was supposed to improve Clemson's defense, but the unit has been inconsistent.
