Well ESPN ranks Duke and UNC as the greatest college basketball rivalry. I've read Rick Bozich column giving reasons why the UofL-UK rivalry is better. I don't know how serious Bozich was being or how thorough he was on researching his facts however after engaging in a mini-debate on Facebook I wanted to ask Cardinal Nation and other CC'ers what they think is the best rivalry. I could offer my opinion but I am pretty bias. I would love to hear some objectivity. Thanks.
