The Tar Heels just kept missing. And with about 10 minutes left, trailing by 14 to Ohio State, Williams benched his starters and put in three walk-ons and two reserves.
Yes, the Tar Heels were that bad.
They shot below 30 percent from the floor, and lost to the sixth-ranked Buckeyes at the Dean Smith Center 74-49.
It was the fewest number of points scored in a game since it scored 49 against Virginia January 2018.
The Tar Heels have lost two of their last three games, and the schedule is not getting any easier. The Tar Heels face No. 5 Virginia on Sunday.
The Tar Heels start to Wednesday's game seemed promising. They hit their first two shots — a layup by Garrison Brooks and a 3-pointer by Leaky Black — and led 5-0.
But that lead did not last long.
UNC freshman forward Armando Bacot went down with ankle injury with about 12 minutes left in the first half. He did not return.
After his injury, the Tar Heels struggled in the paint and could not keep Ohio State off the glass.
In the first half, the Tar Heels kept it close by not turning the ball over. They trailed by three points at halftime.
But in the second half, everything began to unravel.
After Ohio State took a nine-point lead with a little more than 17 minutes left, Anthony hit two consecutive 3-pointers on back-to-back possessions to cut the Buckeye's lead to three points with about 16 minutes left.
But that was the closest the Tar Heels would get. The Buckeyes extended their lead 14 points with about 10 minutes remaining.
Ohio State's E.J. Liddell capped off the 13-2 run with a fast break dunk.
The Buckeyes kept extending their lead.
With four minutes left, the Tar Heel fans began to leave, and all that was heard were the cheers of the Ohio State fans left in the arena.
Ohio State outscored UNC 35-13 over the final 15 1/2 minutes to break the game open. The lead steadily grew until the Buckeyes had surpassed last January's 83-62 win by Louisville here that stood as the Tar Heels' worst in the Smith Center under Williams.
The Buckeyes have been dominant since a 64-56 win against Cincinnati to open the season. They had won their past six games by 19 or more points, including a 76-51 victory against No. 23 Villanova. They host Penn State on Saturday in their Big Ten opener.
