Joining the show this week is Virgil Carter, the man many consider to be the founding father of advanced football statistics. Dave, Brian and Virgil look back at the Virgil's playing days when he was suiting up at quarterback for the Bears while studying for his MBA at Northwestern during the off-season. It was there at Northwestern that he published his first paper, Operations Research on Football. That paper introduced the idea of expected point value based on game situation, an idea that is still at the core of advanced football analysis. Virgil also talks about what it was like to play under head coach Paul Brown, and why if it weren't for him, Bill Walsh might have never needed to create his "west coast" style passing offense.
