1. Carolina's worst previous home loss in the Roy Williams era was a 16-point defeat to Duke in 2013. Saturday's 21-point loss eclipsed that mark, and deservedly so. It was poor in every possible facet of the game.
2. The game was such a complete team breakdown that it would be difficult to identify one key area. Louisville was hot from the perimeter early, and it was as if the Tar Heels never really recovered. There was exactly one moment--when Carolina closed to 38-28 in the first half and appeared to be making a push--that it felt like the home team had any momentum at all.
