Have you picked your NCAA basketball brackets yet? When you’re done, listen to this week’s podcast with Mark Yost, author of Varsity Green: A Behind the Scenes Look at Culture and Corruption in College Athletics. You may know Mark from his excellent sports reporting at the Wall Street Journal. In our ten-minute conversation, I ask about NCAA rule-breaking, whether sports-obsessed universities have lost sight of their educational missions, and if politicians in Washington have any business mucking around in the debate over the BCS.
