CHAPEL HILL, N.C. — North Carolina's season looked sunk after a four-game losing streak marred by penalties, bad defense and inconsistent offense. One clutch drive might have allowed the Tar Heels to change course and restore some confidence. T.J. Logan scored on a 2-yard run with 11 seconds left to help North Carolina rally past Georgia Tech 48-43 on Saturday night, earning a wild win that gave UNC its first Atlantic Coast Conference victory.
