This UNC squad was the first ACC team to ever win a 'chip. And they did it the hard way. Over the course of the season, they won seven games by five points or less. They went into overtime four times. In the national semifinal, they endured three overtimes to beat Michigan State. Then, tasked with the job of knocking off a Kansas team that featured Wilt Chamberlain in the middle, they went to triple overtime again to earn a victory. So, how'd they manage to do it? Kearns offered up an awesome explanation for it. "We're a chilly club," he said after the Kansas battle. "We play it chilly all the time. I mean, we just keep cool." They must have had ice in their veins to make it through that season undefeated.
