The line should be 45-50 points at least.
They score on the road around 55 points when they lose the game, make it 60 if you wish ---> take 60 plus the spread it's 90 and 60 --> 150 pts and the line is around 155 pts there, and that assuming they reach 60 points.

I think more like 95 - 50 is reasonable for a score but that is around 45 pts difference, so why the spread is so low here for North Carolina?
