Mack Brown and North Carolina suffered a disappointing 31-27 loss to Virginia on Saturday night.

The defeat ends UNC’s bid at a perfect season and will certainly knock it out of the top 10 when the new AP Top 25 is released on Sunday. The loss also complicates Carolina’s path to the ACC Championship Game.

There were no apparent warning signs that a game like this was coming for the Tar Heels. Carolina had been dominant in recent weeks and was coming off of a 41-31 win over Miami last weekend in Chapel Hill.

So what went wrong? Brown told reporters after the game that UNC was missing an “edge” on Saturday night.

“I think the edge is probably it,” Brown said when asked what was missing. “You don’t drop that many balls if you have an edge and the problem is some did and some didn’t. There’s some that played great and that’s what we’ll see when we look at it. Some played their hearts out and are really disappointed and some weren’t as prepared and didn’t play as well. And this is a team game. You see upsets all over the country every day and it’s just disappointing.

“When you see it, you try hard for seven straight days to make sure it doesn’t happen. And then it does and that team (Virginia) didn’t have any confidence coming in because they hadn’t played very well.”

Carolina’s wide receiver room had a tough night as it dropped numerous passes from Drake Maye. Maye was also off target on a few throws he usually makes. He went 24-of-48 in the loss, making this his first-ever collegiate game where he started and completed just 50% of his passes.

North Carolina is now 6-1 on the season and will face Georgia Tech on the road next week.
