UNC fan takes advantage of ex-Duke star Irving's flat earth theory

If you haven't heard yet, Kyrie Irving thinks the earth is flat. No, like really, he does.

Irving spent one year at Duke before taking his talents to the NBA and becoming the No. 1 overall pick of the Cleveland Cavaliers. He was planning to major in sociology or psychology.
