With the National Football League's pre-season about to begin, our guest this week is former NFL commissioner Paul Tagliabue. Tagliabue served as NFL commissioner from 1989 to 2006; he kicked off a new series on "Leadership and Globalization in Sports" at the University of Kansas Dole Institute of Politics in November 2008. Join us at 8:00 Sunday night for Tagliabue's unique perspective on sports in America and around the world.
