Duke Blue Devils vs North Carolina Tar Heels

College basketball s greatest rivalry. Being seven miles apart helps, but so does the image of Dean Smith or Roy Williams on one sideline and Mike Krzyzewski on the other. Throughout the last quarter-century, the ACC championship and a Final Four berth has so often been awarded to one of these teams. That gives their annual home-and-home battles an electricity that is unmatched at any other time in the college basketball regular season. There are any number of games to choose from for the greatest showdown, but one of the earliest Dean Smith-Coach K matchups was the best. With Eric Montross and Christian Laettner battling in the paint for 40 minutes, the Tar Heels upset the No. 1 Blue Devils, who would win their first-ever national championship two months later. The teams have met for a ridiculous 240 games and UNC leads 133-107.
