James Harold "Sleepy Jim" Crowley (September 10, 1902 – January 15, 1986) was an American football player and coach.

He gained fame as one-fourth of the University of Notre Dame's legendary "Four Horsemen" backfield where he played halfback from 1922 to 1924.

The Blues put on a good show by driving to a 34–0 triumph, with Crowley scoring three touchdowns and Stuhldreher booting two field goals and three extra points.

The defense was led by two-time All-American lineman Alex Wojciechowicz, who later starred professionally for the Detroit Lions and was named to the Pro Football Hall of Fame.

Another "Block of Granite", Vince Lombardi, would gain fame as a championship coach for the New York Giants and Green Bay Packers.

In 1942, he served as the head coach for the North Carolina Pre-Flight School team and led the Cloudbusters to an overall record of 8–2–1.

Following the 1946 season, Crowley stepped down as commissioner to become part-owner and coach of the AAFC's worst team, the Chicago Rockets.
