Some context: Elmer Francis Layden (May 4, 1903 - June 30, 1973) was an American football player, coach, college athletics administrator, and professional sports executive. He played college football at the University of Notre Dame where he starred at fullback as a member of the legendary "Four Horsemen" backfield. Layden played professionally in the original AFL in 1925 and 1926 with three different clubs, the Hartford Blues, the Brooklyn Horsemen, and the Rock Island Independents. He began his coaching career during the same two seasons at Columbia College in Dubuque, Iowa, now known as Loras College.
After his playing days, Layden was head football coach at Columbia College (Dubuque, Iowa) in 1925-26, where he compiled an 8-5-2 record. From 1927 to 1933 he was head coach at Duquesne University in Pittsburgh, going 48-16-6 and winning the 1933 season's Festival of Palms Bowl (a precursor to the Orange Bowl) on New Year's Day, 1934. Also in 1934, he became head coach and athletic director at Notre Dame, three years after his legendary mentor Knute Rockne was killed in an airplane crash on March 31, 1931. Layden led the Irish for seven years and posted an overall 47-13-3 docket. His 1935 squad posted one of the greatest wins in school history by rallying to defeat Ohio State 18-13. His 1938 team finished 8-1, losing only to USC in the season finale. This loss cost them a possible consensus national championship, but the team was named national champion by the Dickinson System. Like Rockne before him, Layden was a goodwill ambassador for Notre Dame. He was able to schedule a home-and-home series with Michigan after meeting with Fielding H. Yost, healing a rift between the two schools. The two teams had not met since 1909, when, after eight straight losses to the Wolverines, the Irish posted their first win. They were scheduled to meet again in 1910, but Michigan canceled the game and refused to play the Irish again. By the time they met again in 1942-43, Layden had left Notre Dame and Frank Leahy had taken his place. Unlike the easygoing Layden, Leahy was intense, and after the Irish had thrashed Michigan by a score of 35-12 in 1943, Wolverine coach and athletic director Fritz Crisler never scheduled the Irish again. While Layden was a solid, competent coach, he was subjected to criticism during his later years at Notre Dame. Critics felt that his teams played too conservatively and lacked scoring punch. Consequently, it was felt that they lost games they should have won.

Some context: William Miller Edwards (June 21, 1905 - June 12, 1987) was an American football player and coach. He served as the head football coach at Western Reserve University, Vanderbilt University and Wittenberg University in a career lasting more than 30 years, compiling a win-loss-tie record of 168-45-8. Edwards also coached the Detroit Lions of the National Football League (NFL) from 1941 to 1942, tallying a 4-9-1 record, and served as an assistant coach for the NFL's Cleveland Browns in the late 1940s. Raised near Massillon, Ohio, Edwards was the son of an immigrant from Wales who worked in the area's coal mines.
Having built a strong record at Western Reserve, Edwards was in the running for head coaching roles at a number of larger universities and professional teams. He met with officials at Marquette University and was considered a candidate for coaching duties at Colorado University and for the National Football League's Detroit Lions. After visiting with Lions owner Fred Mandel, Edwards ultimately was hired in February 1941 to succeed George Clark. Both Edwards and Dugan Miller signed two-year contracts. Edwards was given a $10,000 annual salary ($166,380 in 2017 dollars), more than double the $4,420 he was paid at Western Reserve. Edwards's stint as the Lions coach was unsuccessful. He guided the team to a 4-6-1 record in 1941, and Mandel fired him after three straight losses to begin the 1942 season as the team's roster was depleted by players' service in World War II. Detroit went on to lose all the rest of its games after John Karcis was named his replacement. Edwards enlisted in the U.S. Navy later in 1942 as America's involvement in the war intensified. While in the military, he served at St. Mary's Pre-Flight, a training program in California, and coached the Air Devils football team there. He also served at a base in Pensacola, Florida. Edwards was discharged in 1946, and spent a year in the sporting goods business in Cleveland, Ohio before reuniting with Brown, who had become the first coach of the Cleveland Browns in the All-America Football Conference (AAFC). Edwards took a position as a tackle coach and remained with the team for two seasons. He coached tackles including Ernie Blandin, Lou Rymkus and future Pro Football Hall of Fame member Lou Groza. The Browns won the AAFC championship in both of Edwards's years as an assistant; the team won all of its games in 1948, turning in professional football's first perfect season.
