Joe Lunardi is assistant vice president for marketing and communications at St. Joseph's University. He also is the radio analyst for St. Joseph's men's basketball games. But that's not why his name has been popping up during virtually every ESPN telecast the last couple of weeks. Lunardi is the inventor and foremost practitioner of bracketology. If you haven't heard of bracketology, you probably fill out your NCAA tournament office pool using favorite nicknames. Lunardi predicts the NCAA tournament field in advance for ESPN. You can find his constantly updated predictions on ESPN.com and Lunardi himself all over ESPN's airwaves this week. Last week, Lunardi spoke with Inquirer staff writer Mike Jensen.
