 The way things worked back in college football back then, the schedules were not set many years in advance. They were really only set like a year or so in advance, only today. Right now, Michigan knows five years from now who they're going to be playing. But back in those days, they set the schedule like the year before. And Michigan had always only ever played teams from the north, teams from either the Midwest or maybe the east. They'd never played a team from the south.
