Walston: Assignment Football Posted Sep 18, 2010 It's one thing to know what your opponent is going to do. It's quite another to stop it. The Georgia Tech Yellow Jackets ran Paul Johnson's flexbone offense to near perfection on Saturday, and the end result was a 30-24 victory over North Carolina. Senior linebacker Quan Sturdivant said after the game that it's difficult to maintain the defensive discipline required when facing Johnson's offense. (Tar Heel Blue)
