The fates of Michigan and Notre Dame have been intertwined since that cold November day in 1877 when the Wolverines literally taught the game of football to an eager group of Notre Dame students. Richly illustrated and now including games through the 2006 season, Natural Enemies weaves these two chronologies together to produce a college rivalry book like no other.
