When the Duke Blue Devils (18-5) and North Carolina Tar Heels (21-4) tip off inside Cameroon Indoor Stadium on Thursday night, one of college basketball's most storied rivalries will be renewed for the 243rd time.
Not only do the two schools often compete for ACC titles, but in the last 96 meetings, each team has won 48 times and scored exactly 7,437 points. No joke.
But does that make it the greatest rivalry in men's hoops? What about Indiana vs. Purdue or Cincinnati vs. Xavier -- who play 12 miles from each other.
