I'm not that optimistic.
The offense showed that it can be stopped today, too. The two sides don't play together. The defense is the more glaring liability, but the offense is also prone to screw-ups. Drake Maye is going to get pressured a lot more going forward. I hope that Downs and Greene will be healthy and able to help out.
I also don't know how good the other teams in our division are, but I don't think they're all barely beating their cupcakes like the Heels. UNC could have easily lost all three of the cupcakes. None were decisive wins.
