Good analysis. I also fear UNC will be better than most even thought they would be. Their early season play hasn't been perfection, but it is early in the season.
The good news is, to me they don't look indestructible. Even with improvement throughout the season, they are not that far ahead of the pack. It seems to me that there are several teams that could challenge them for the NC, most importantly Duke. Granted it will be a harder road, but at least we are in the mix.
