Tar Heels' Defense Aiming to Stay Fresh With Substitution Pattern Posted Sep 4, 2024 Kaimon Rucker gave a positive review to Geoff Collins based on the substitution pattern the Tar Heels' defense employed on Thursday vs. Minnesota. Rucker, along with others on UNC's defense, found delight in the ability to check out of the game on occasion and check into the game fresh. North Carolina played 20 players on defense in the 19-17 win. (Inside Carolina)
