The Michigan Wolverines football team represents the University of Michigan in college football at the NCAA Division I Football Bowl Subdivision level. Michigan has the most all-time wins in college football history. Michigan began competing in intercollegiate football in 1879. The Wolverines joined the Big Ten Conference at its inception in 1896, and other than a hiatus from 1907 to 1916, have been members since. Michigan has won or shared 44 league titles, and since the inception of the AP Poll in 1936, has finished in the top 10 a total of 39 times. The Wolverines claim 11 national championships, most recently that of the 1997 squad voted atop the final AP Poll. From 1900 to 1989, Michigan was led by a series of nine head coaches, each of whom has been inducted into the College Football Hall of Fame either as a player or as a coach. The Michigan Wolverines have featured 87 players that have garnered consensus selection to the College Football All-America Team. Three Wolverines have won the Heisman Trophy: Tom Harmon in 1940, Desmond Howard in 1991, and Charles Woodson in 1997. Gerald Ford, who later became the 38th president of the United States, started at center and was voted most valuable player by his teammates on the 1934 team.
