Iowa Mark Catlin decided to go to law school at the
University of Iowa. These changes greatly hampered play in 1906. Conference players who were to be seniors were all ruled ineligible, because they had already played three years of competition. Players who were to be freshmen also sat out. Only players who were to be sophomores and juniors were allowed to play. Iowa finished with a 2–3 record in 1906. The most notable game of the 1907 season was the "rabbit game" against
Wisconsin. After two easy wins to start the season, Iowa held a 5–0 halftime lead over Wisconsin when the two teams lined up for the second half kickoff. A rabbit ran out of Wisconsin's end zone and sprinted 110 yards downfield into Iowa's end zone. Wisconsin returned a punt late in the game for a touchdown, following the path of the rabbit, and gave the Badgers a 6–5 win. The Hawkeyes were amusingly convinced that it was the rabbit that had jinxed the team. Before their Wednesday practice for the weekend's
Illinois game, the team had a rabbit hunt. Catlin found and shot the unlucky rabbit, and before the game with Illinois, the members of the Hawkeye team rubbed the dead rabbit's left hind foot for good luck. It must have worked; Iowa won, 25–12. Iowa finished the year with a 3–2 record. Catlin returned for the 1908 season. The season opening game against
Coe College set the tone for the season. Two years earlier, Coe protested a game against Iowa. Iowa had won, 15–12, but there was considerable controversy surrounding the win. Iowa trailed late in the game, and Coe officials complained that the timekeeper had given the Hawkeye team extra time to get in position for the game winning score. The Hawkeyes were determined to leave no doubt this time. They didn't. Iowa won, 92–0. It is still the second largest margin of victory in school history. However, it was a Pyrrhic victory. Five prominent players, including Carroll "Chick" Kirk and Walter "Stub" Stewart, were badly injured and did not regain their effectiveness all year. As a result, Iowa stumbled to a 2–5 record. In 1908, Catlin acquired a live black bear named Burch when visiting his dad back in Wisconsin. Burch served as the mascot for the Iowa Football team from 1908 to 1910. Mark Catlin, law degree in hand, left Iowa after the 1908 season. He had a 5–7 record in 1907–1908, and a 2–3 record in 1906. Despite the record, Catlin was a very innovative coach. He introduced the team to the game of handball to develop the team's quickness. He was also one of the first coaches to give his players oxygen when they became winded. In addition to coaching football, Catlin served as Iowa's track and cross country coach for three years from 1906 to 1908. He left to coach at
Lawrence University.
Lawrence Catlin began to make his mark on Lawrence football in 1910, when the Vikings played to a 6–6 tie with Wisconsin. For the next four seasons, Lawrence was the unquestioned powerhouse of small college football in the state. Catlin's teams won four consecutive Wisconsin Intercollegiate championships from 1911 to 1914 and gave up just one touchdown to a small college opponent. In that stretch, Lawrence outscored its opponents 485–143. Catlin stepped away from football following the 1918 season. He served in the
Wisconsin State Assembly from 1921 to 1923 as a
Republican. His son,
Mark Catlin Jr., also served in the Wisconsin State Assembly and was the speaker. After being defeated in the Republican primary in 1922, he returned to his law practice. Catlin returned to football in 1924 and coached the Vikings to a 4–1–1 record and their second
Midwest Conference championship. He coached for three more seasons before leaving Lawrence for good in 1927. Catlin was a master strategist and psychologist when it came to gridiron tactics. He insisted on skin-tight dark blue jerseys, to make his team look smaller. This was the rough-and-tumble age of football, and Catlin wanted his men to be the toughest. He allowed minimal padding, and the men wore no shoulder pads or helmets. Catlin once said, "My theory on shoulder pads is that they are unnecessary because nature has provided protection at the vital points." Catlin earned the moniker "Coach of Champions" during his 14 years as the football coach at Lawrence University. He won five conference championships, and his record of 55–29–7 ranks him third on the school's all-time wins list. Catlin worked as an attorney until his death of a heart attack in 1956. ==Head coaching record==
