UNC-Duke stands the test of time Posted Feb 12, 2014 As the Tar Heels and No. 8 Blue Devils prepare to face off Wednesday, it marks the 137th consecutive time that at least one school has been ranked in the Associated Press poll. There's an ebb and flow to the series. The Blue Devils have won seven of the last nine since 2010, but that was essentially seen as a response after the Heels had won seven of nine from 2005-09.
