Just for fun I looked at the top ACC Teams and calculated for their ACC games their margin on the road, their margin at home and difference in their margin between home and away.
In case that isn't clear we are beating ACC foes on the road by an average of 1.25 points, but beating them at home by a whopping 34 point average. So, on average, we are 32.75 points better at home than on the road. Compare that with UVa, which is still better at home than on the road, but is much more consistent.
Obviously this is based on only a small number of games, but it's still kind of interesting.
