Here's my column about Duke and UNC's wonderful basketball rivalry.
I think sometimes we take this rivalry for granted, since it comes around like clockwork 2-3 times every year in February and March. But we shouldn't.
It's an extraordinary rivalry, really, affected so much by geography (Chapel Hill and Durham are so close to each other that Mike Krzyzewski and Dean Smith once used the same piano teacher for their daughters). But it's also affected by the fact that the two teams are so great so often -- one or the other (or usually both) have been nationally ranked for every meeting since 1955.
I wrote in this column I believe it to be the best rivalry in all of sports.
