PITTSBURGH — Coach Mack Brown had dried off, but still dripped with rethinking the end of regulation and what might’ve been a special victory for his North Carolina team that instead evaporated into a loss.

The Tar Heels fell to No. 25 Pittsburgh 30-23 in overtime Thursday night at Heinz Field, a winding Atlantic Coast Conference football experience that swung North Carolina from the brink of becoming a blowout victim to the verge of winning in the final minute of regulation.
