When the Duke Blue Devils (18-5) and North Carolina Tar Heels (21-4) tip off inside Cameron 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: In the past 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 3.3 miles from each other. You can't forget about Kentucky vs. Louisville, either.
Now it's your turn to weigh in and cast your ballot on the best rivalry in men's college basketball.

Indiana and Purdue tip off at 7 p.m. ET on ESPN2, while Duke and North Carolina get started at 8 p.m. ET on ESPN.
