Duke is 5-9 vs the spread in ACC play. During the 7 game win streak, they are 3-4. One of the wins was UNC at home, and the two other wins were @UVa and @Notre Dame. During the streak, Duke is 1-3 at home against the spread, and 2-1 on the road. The one road loss against the spread was Wake, which seems to be a team that is engineered to give a coach reluctant to play large people a problem. Wake is also responsible for one of the home losses against the spread.
This feels like a "degree of difficulty" game that Duke players might be motivated for.
