Why are some so obsessed with sports? An expert weighs in

We all probably know at least one person who is all about sports.  But, just why are some of us so into sports?  To answer that question, WTIP invited  Doug Hartmann, professor, and chair of sociology at the University of Minnesota, to join The Roadhouse.  WTIP volunteer Brian Neil spoke with Hartmann about the psychology of being an avid sports fan.
