The theme of this week's episode is the rise and fall of great pigskin powers. The game? 1937 Michigan vs. Chicago. If these teams met at the turn of the 20th century it would have been one of the biggest games in the country. I'm talking Stagg vs. Yost huge. But on that November 6th day 84 years ago back in 1937, it was about two once-great programs in tatters.
