This is the second straight road game for the Tar Heels, which gives us permission to circle back to a developing trend with Hubert Davis’ team. Their tempo rating is high — not Arizona or Alabama but among the faster top teams in the country — so UNC gets high totals but their elite defensive form of late has kept scoring low enough for unders to cash. Since Jan. 1, the under is 7-1 in UNC games and in each of the last three games the under has cleared the total by at least nine points.
