While many trace Knute Rockne's debut as a Notre Dame football coach to the war-torn 1918 season, or in 1914 when he became an assistant coach under
Jesse Harper, his first position was actually for the Corby and
Sorin Hall football teams as a student-athlete in 1912 and 1913. These teams represented residence halls on the university grounds that competed against one another in various sports, the most popular of which was football. The term for these competitions is colloquially known as
interhall sports. Ironically, while Rockne holds the highest winning-percentage of any major college football coach, his overall record in the interhall football league was a paltry 2–5–4 across two seasons. During 13 years as head coach, Rockne led Notre Dame to 105 victories, 12 losses, 5 ties, and 3 consensus national championships, which included 5 undefeated and untied seasons. Rockne posted the highest all-time winning percentage (.881) for a major college football coach. His schemes utilized the eponymous
Notre Dame Box offense and the
7–2–2 defense. Rockne's box included a
shift. The backfield lined up in a
T-formation, then quickly shifted into a box to the left or right just as the ball was snapped. Rockne also recognized that intercollegiate sports had a show-business aspect. Thus he worked hard promoting Notre Dame football to make it financially successful. He used his charm to court favor from the media, which then consisted of newspapers, wire services and radio stations and networks, to obtain free advertising for Notre Dame football. He was successful as a promoter for
South Bend-based
Studebaker and other products. Through sustained effort, work with Studebaker, several side jobs, and coaching at the University of Notre Dame, Rockne eventually earned an income of $75,000 from all his financial activities combined.
1918–1930 During the war-torn season of
1918, Rockne took over from his predecessor
Jesse Harper and posted a 3–1–2 record, losing only to the
MAC Aggies (now the MSU Spartans). He made his coaching debut on September 28, 1918, against
Case Tech in
Cleveland, earning a 26–6 victory. In the backfield were
Leonard Bahan,
George Gipp, and
Curly Lambeau. In Gipp, Rockne had an ideal handler of the
forward pass. Rockne handled the line and
Gus Dorais handled the backfield of the
1919 team. The team went undefeated and was a national champion, though the championship is not recognized by Notre Dame. Gipp died on December 14,
1920, just two weeks after being elected Notre Dame's first All-American by Walter Camp. He likely contracted
strep throat and pneumonia while giving
punting lessons after his final game, on November 20 against Northwestern University. Since antibiotics were not available in the 1920s, treatment options for such infections were limited and they could be fatal even to the young and healthy. It was while on his hospital bed and speaking to Rockne that he is purported to have delivered the line "win just one for the Gipper".
John Mohardt led the
1921 Notre Dame team to a 10–1 record with 781 rushing yards, 995 passing yards, 12 rushing touchdowns, and 9 passing touchdowns.
Grantland Rice wrote, "Mohardt could throw the ball to within a foot or two of any given space" and noted that the 1921 Notre Dame team "was the first team we know of to build its attack around a forward passing game, rather than use a forward passing game as a mere aid to the running game". Mohardt had both
Eddie Anderson and
Roger Kiley at
end to receive his passes. The national champion
1924 team included the "
Four Horsemen" backfield of
Harry Stuhldreher,
Don Miller,
Jim Crowley, and
Elmer Layden. The line was known as the "Seven Mules". The Irish capped an undefeated 10–0 season with a victory over
Stanford in the
Rose Bowl. For all his success, Rockne also made what an
Associated Press writer called "one of the greatest coaching blunders in history". Instead of coaching his
1926 team against
Carnegie Tech, Rockne traveled to Chicago for the
Army–Navy Game to "write newspaper articles about it, as well as select an All-America football team". Rockne wrote of an attack on his coaching in the
Atlanta Journal, "I am surprised that a paper of such fine, high standing [as yours] would allow a zipper to write in his particular vein ... the article by
Fuzzy Woodruff was not called for." On November 10, 1928, the Fighting Irish were tied with
Army 0–0 at the end of the half. Rockne entered the locker room and told the team the words he heard at Gipp's deathbed in 1920: "I've got to go, Rock. It's all right. I'm not afraid. Some time, Rock, when the team is up against it, when things are going wrong and the breaks are beating the boys, tell them to go in there with all they've got and win just one for the Gipper. I don't know where I'll be then, Rock. But I'll know about it, and I'll be happy." This inspired the team, who then won the game 12–6. The phrase "Win one for the Gipper" was later used as a political slogan by
Ronald Reagan, who in 1940 portrayed Gipp in
Knute Rockne, All American. Both the
1929 and the
1930 teams went undefeated and were national champions. According to interviews, Rockne considered his 1929 team his strongest overall. Rockne also said he considered his 1930 team to have been his best offensively before the departure of
Jumping Joe Savoldi. Rockne was struck with illness in 1929, and the
de facto head coach was assistant
Tom Lieb. Rockne's all-time All-America
backfield was
Jim Thorpe,
Red Grange,
George Gipp, and
George Pfann. ==Personal life==
