North Carolina’s offense was hot and cold in its 38-7 victory over Duke on Saturday at Kenan Stadium.

The Tar Heels started slowly, exploded for a bit more than two quarters, hit the skids again in the third quarter managing just nine total yards, and erupted over the final period for 184 yards.

Carolina scored touchdowns on offensive plays that went 75 and 63 yards, and 31 of the Tar Heels’ 38 points were scored by the offense.
