1917 saw the rise of another Southern team in Centre of Danville, Kentucky. In 1921 Bo McMillin-led Centre upset defending national champion Harvard 6 to 0 in what is widely considered one of the greatest upsets in college football history. The next year Vanderbilt fought Michigan to a scoreless tie at the inaugural game at Dudley Field (now Vanderbilt Stadium), the first stadium in the South made exclusively for college football. Michigan coach Fielding Yost and Vanderbilt coach Dan McGugin were brothers-in-law, and the latter the protégé of the former. The game featured the season's two best defenses and included a goal line stand by Vanderbilt to preserve the tie. Its result was "a great surprise to the sporting world." Commodore fans celebrated by throwing some 3,000 seat cushions onto the field. The game features prominently in Vanderbilt's history. That same year, Alabama upset Penn 9 to 7.
