1947 national champion in the Associated Press's final poll. The 1947 Notre Dame Fighting Irish football team represented the University of Notre Dame during the 1947 college football season. The Irish, coached by Frank Leahy, ended the season with 9 wins and no losses, winning a share of the national championship. The 1947 team became the sixth Irish team to win a national title and the second in a row for Leahy. The squad is the second team in what is considered to be the Notre Dame Football dynasty, a stretch of games in which Notre Dame went 36–0–2 and won three national championships and two Heisman Trophies from 1946 to 1949. The 1947 team was cited by Sports Illustrated as part of the second best sports dynasty (professional or collegiate) of the 20th century and second greatest college football dynasty. Wiki link
