Tar Heels Struggle To Move Chains On Fourth Down In Loss To Pitt Posted Oct 5, 2024 Mack Brown left the UNC offense on the field for six fourth down attempts. He even told defensive coordinator Geoff Collins during the game when he was planning to go for it on fourth down to get the defense ready. But the aggressive approach didn't match the results, as UNC went 2-6 on fourth downs against Pitt on Saturday in its 34-24 home loss. (Inside Carolina)
