One can see why Williams is concerned. The Tar Heels have now allowed opponents to convert 10 or more 3-point shots in four consecutive games. Last season, 3-point defense was UNC's biggest weakness and it is continuing to plague it this season.
To put that number in perspective, last season North Carolina allowed opponents to hit an average of 9.6 3-pointers a game, a number only topped by eight other teams.
Equally concerning was the ease with which Michigan scored. The Wolverines shot 57.4 percent for the game and three players scored 18 or more points.
UNC will have to correct its defense quickly with matchups against No. 1 Gonzaga and No. 10 Kentucky looming in the near future.
Rough day for the starting lineup
It was not an encouraging performance for the North Carolina starting lineup. Just 4:12 into the second half, Williams saw his team go down by 12 points and he quickly yanked his starting unit. By the time the starters re-entered the game at the 11:21 mark, Michigan had opened up a 19-point lead. Williams did not mince words when asked about pulling his first team after the game.
"It was because they stunk it up," Williams told ESPN. "Every one of them stunk it up, and so did I."
He wasn't wrong. It was the lowest scoring output by his starting five this season at 49 points. First-year guard Coby White led the five with 12 points and graduate guard Cameron Johnson, the team's leading scorer heading into the matchup, was held to five points on 2-7 shooting.
Only time will tell whether the performance was an aberration, or a warning of things to come.
Where were the UNC big men?
In the team's season-opening win over Wofford, sophomore forward Garrison Brooks exploded for a career-high 20 points, leaving fans wondering if he was about to experience a breakthrough campaign.
Since that game, Brooks has struggled and so has fellow sophomore forward Sterling Manley. Brooks, who's averaging 9.3 points per game on the season, has only reached double figures in points twice since the Wofford game.

Although he scored 10 points Wednesday night, four of those points came in the opening minute. In recent games, Brooks has failed to recreate the aggressive play he had in the first game of the season.
Manley has taken a step back thus far in his second season with the team, only averaging 4.5 points after scoring 5.4 per game last season. In his past three games he has only logged 19 minutes of playing time, accumulating five fouls, five turnovers, six rebounds and only two points.
Along with senior forward Luke Maye, who has seen his scoring output go down 2.9 points per game so far this season, the UNC frontcourt has not taken the big step forward Williams would have liked.
If the problem does not get solved soon, UNC could move to a small-ball lineup like the team did in the 2017-2018 season.
