CHAPEL HILL, N.C. -- Marquise Williams threw five first-half touchdown passes and T.J. Logan scored four touchdowns to help North Carolina to a record-setting 80-20 victory over Old Dominion on Saturday.
The Tar Heels set all-time records for points and touchdowns by the midpoint of the third quarter, and Williams set the single-game record for total yards on the Tar Heels' fourth snap of the second half.
Just two of North Carolina's 11 TDs came on possessions longer than 1 minute, 44 seconds. By mutual agreement of the coaches, the fourth quarter was shortened from 15 minutes to 10.
Williams finished 20 of 27 passing for 409 yards and rushed for 60 more, helping North Carolina to a school-record 721 yards. Williams tied the UNC mark for passing touchdowns and was third in single-game total yards by halftime.
The point total was the second-most in ACC history, surpassed only by Clemson's 82 in 1981 against Wake Forest.
The Tar Heels (6-5) became bowl-eligible with their fifth consecutive victory, their longest streak since 2001. The Monarchs (8-4), in a transition season from the Football Championship Subdivision to Football Bowl Subdivision, had their four-game win streak snapped.
North Carolina outscored ODU 68-7 in the middle two quarters, behind a combined seven touchdowns from freshmen Logan and Ryan Switzer. Logan had two 1-yard runs, a 63-yard run and a 99-yard kickoff return. Switzer scored on receptions of 43 and 57 yards and added a 64-yard punt return that put the Tar Heels ahead by the final margin with 3:50 left in the third quarter.
Switzer's punt-return score was his fourth in three games and tied the ACC single-season record.
The Tar Heels outscored ODU 35-0 in the second quarter, tying the school record for points in a quarter. Old Dominion, trying for its second victory over an FBS team after winning 59-38 at Idaho two weeks earlier, couldn't get its high-powered offense cranked up to match or even stay close to the Tar Heels.
North Carolina's last 23 touchdowns, and all 11 against Old Dominion, have been scored by freshmen or sophomores.
