1906–1917 Stanford rugby teams

In its first season of rugby, Stanford retained head football coach James F. Lanagan as its first rugby coach. Lanagan had coached the football team for three years, including an undefeated 1905 season.[7] With no experience playing or coaching rugby, Lanagan initially offered his resignation, but Stanford insisted he stay on, so he traveled to Vancouver, British Columbia to study the sport.[4][7][8] Stanford won its first five games, including two wins over a visiting club team from Vancouver. As winners of the first Big Game against California played as rugby, Stanford competed against Vancouver-area club teams for the Cooper Keith Trophy, losing two games and tying one.[9]

In Stanford's second season of rugby, Jimmy Lanagan returned as coach and the team finished 8–4. Stanford continued its series with Nevada, Vancouver, and Victoria and added games against Bay Area club team the Barbarians and a Los Angeles club called the Castaways. Stanford won its second Big Game rugby match, earning a second straight tournament in British Columbia.[9]

Lanagan returned for his final year as Stanford's coach and the team finished 12–2, winning not only its third consecutive Big Game, but also going on to win the Cooper Keith Trophy in the end-of-season Vancouver tournament. Stanford added two games against San Francisco's Olympic Club and played a final game against the Australian national team, the Wallabies.[9]

Following Lanagan's departure, George Presley was named Stanford's new rugby coach. Presley played one year of rugby under Lanagan in 1906 and had been an assistant coach in 1907 and 1908. Presley also coached Stanford's baseball team. Stanford won its first eight games—seven by shutout—but then lost Big Game for the first time in seven years.[7][9]

In Presley's second year as coach, Stanford was led by Ben Erb and Jim Arrell. The season was almost identical to the previous year: the team won its first seven games by shutout, and then lost Big Game to undefeated California. Stanford led in that game 6–0, but did not score again as California won 25–6. This Big Game is recognized as the first intercollegiate game to feature card stunts.[7][9]

In the 1911 season, Stanford went 10–3 and added USC to the schedule, as the school dropped football in favor of rugby.[9]

In Presley's last year as coach, Stanford finished with a 5–3–1 record, its worst record of the rugby era. Stanford avoided a fourth straight loss in the Big Game by tying California. Despite an outstanding 30–8–1 overall record as coach, coach Presley was 0–3–1 against the Bears.[7][9]

Floyd C. Brown succeeded George Presley as coach. Like Presley, Brown had played for and served as an assistant under the previous coach. Stanford finished with an 8–3 record, including its first Big Game win in five years, led by Danny Carroll, who had won a gold medal in the 1908 Summer Olympics as a member of the Australia national rugby union team and who was now earning a degree in geology from Stanford. Stanford played its final rugby game against USC, who returned to American football the next year, and suffered two blowout losses to the famed New Zealand All Blacks, who were on a North American tour.[7][9]

Brown's second year as coach was the best in Stanford rugby history: the team was undefeated entering the Big Game at California, who was also undefeated. A record crowd of 26,000 turned out to see Stanford defeat the Bears, 26–8. This would be the last Big Game for several years as California returned to football for the 1915 season. Despite Stanford's success in rugby, the previous year's humiliating defeats to the All Blacks and the switch by rivals USC and California to football intensified the sentiment for Stanford to switch back as well.[7][9]

By 1915, there was only one other U.S. college playing intercollegiate rugby: Santa Clara. The rest of Stanford's schedule was made up of local club and all star teams. The team played to a scoreless tie with the Olympic Club team to start the season, but recovered to win the rest of the games on the schedule.[7][9]

In their last full season of rugby, Stanford won all its games except the "Big Game" against Santa Clara, played for the second year at Ewing Field in San Francisco. This was Stanford's first loss since 1913.[9]

Like the two coaches before him, Stanford's new head coach Jim Wylie was a former Stanford player. He had also been a member of the New Zealand All Blacks team that had crushed Stanford's team in 1913. But with World War I imminent, Stanford played just one game, the "Big Game" against Santa Clara, winning 15–11. This was also Stanford rugby's last game as a major sport. The following year, Stanford president Ray Lyman Wilbur canceled all intercollegiate athletic events due to students' enlisting in the military for the war, and due to Stanford's designation as the regional headquarters of the Students' Army Training Corps.[3][7][9][10] When Stanford reformed a team in 1919, the school returned to American football as its major gridiron sport.[3]
