1947 Michigan Wolverines football team

The 1947 Michigan Wolverines football team represented the University of Michigan in the 1947 Big Nine Conference football season. In its tenth year under head coach Fritz Crisler, Michigan compiled a perfect 10–0 record, won the Big Ten Conference championship, and defeated the USC Trojans by a score of 49–0 in the 1948 Rose Bowl game. Although ranked second in the AP Poll at the end of the regular season, the Wolverines were selected as the nation's No. 1 team by a 226–119 margin over Notre Dame in an unprecedented (and unofficial) AP Poll taken after the bowl games. The 1947 team outscored its opponents, 394–53, and has been selected as the best team in the history of Michigan football.

The 1947 Michigan Wolverines included five players who have been inducted into the College or Pro Football Halls of Fame: left halfback Bob Chappuis (who finished second in the 1947 Heisman Trophy voting), right halfback Bump Elliott (who received the Chicago Tribune trophy as the Big Ten MVP), defensive quarterback Pete Elliott, defensive end Len Ford, and tackle Al Wistert. Offensive tackle Bruce Hilkene was the team captain, and quarterback Howard Yerges was the field general who became known as "Crisler's 'second brain.'"Jack Weisenburger was the "spinning fullback" and the 1947 Big Ten rushing leader.

The 1947 Wolverines were the first team fully to embrace the concept of defensive and offensive specialization. Previously, most players had played their positions on both offense and defense. In 1947, Fritz Crisler established separate offensive and defensive squads. Only Bump Elliott and Jack Weisenberger played on both squads. In November 1947, Time magazine ran a feature article about the 1947 Wolverines focusing on the new era of specialization marked by Crisler’s decision to field separate offensive and defensive units. The Time article noted: "Michigan's sleight-of-hand repertory is a baffling assortment of double reverses, buck-reverse laterals, crisscrosses, quick-hits and spins from seven different formations. Sometimes, watching from the side lines, even Coach Crisler isn't sure which Michigan man has the ball. Michigan plays one team on offense, one on defense...Whenever Michigan's defensive team regains the ball, Crisler orders: 'Offense unit, up and out,' and nine men pour onto the field at once." Crisler's single-wing formation in action was "so dazzling in its deception" that the media nicknamed the 1947 team the "Mad Magicians".
