The Four Horsemen

In 1924, Notre Dame football was the biggest sports team in America. Coached by the legendary Knute Rockne, the team featured a fabled backfield that ran roughshod over opponents and into the imaginations of fans across the country. Dubbed the Four Horsemen by famous writer Grantland Rice (and immortalized in a now famous photo of the uniformed quartet on horseback), Harry Stuhldreher, Don Miller, Jim Crowley and Elmer Layden will forever be remembered in sports history. In the three years they were together, they only lost two games. Add a national championship and the fact that all four played ironman football, and a spot on this list is assured.
