Staleys In early July 1920, Trafton signed to play for the
Decatur Staleys in the inaugural season of the
National Football League (known that year as the American Professional Football Association). Trafton appeared in all 13 games for the
1920 Staleys team that compiled a 10–1–2 record and finished in second place in the new league. At the end of the 1920 season, Trafton was selected as a first-team All Pro. The 1920 Staleys included three players who were later inducted into the
Pro Football Hall of Fame: Trafton,
George Halas, and
Jimmy Conzelman. In June 1921, Trafton returned to the Staleys, working in
A. E. Staley's starch plant during the summer. The
1921 Staleys compiled a 9–1–1 and won the first NFL championship in the history of the
Chicago Bears franchise (the Staleys were renamed the Bears in 1922).
Northwestern In 1922, Trafton took leave from professional football to serve as an assistant football coach, with responsibility for the linemen, for
Northwestern University in
Evanston, Illinois. The
1922 Northwestern Purple football team compiled a 3–3–1, and went 1–3–1 against
Big Ten Conference opponents. In February 1923, Trafton was forced to resign his coaching job due to a ruling from the Big Ten Conference prohibiting former professional players to coach in any capacity for a conference team. Northwestern's athletic director,
Dana Evans, said at the time that he accepted the resignation with reluctance and called Trafton "one of the best line coaches in the conference and a large factor in developing the 1922 Purple eleven."
Bears In September 1923, Trafton returned to the NFL as a player with the
Chicago Bears. He continued playing with the Bears through the 1932 season. During Trafton's tenure with the Bears, the Staleys/Bears won NFL championships in 1921 and 1932, and Trafton was selected six times as a first-team All Pro (1920, 1923–1927). According to his biography at the
Pro Football Hall of Fame, he "was one of the first centers to rove on defense and the very first on offense to center the football with only one hand." Although players played both offense and defense in his era, Trafton was primarily a defensive presence — essentially a
middle linebacker in contemporary terms. His offensive performance as a center tended to be perfunctory. His teammate with the Bears for five seasons,
guard Jim McMillen, recalled: "He was a great center on defense but lazy as blazes on offense. Pictures of our games showed George standing with one hand on his hip after passing the ball back and just gawking around.
Herb Stein cured him of that. Stein was playing a roving center about five yards back of the line. He spotted Trafton stargazing, got a flying start, and rammed George squarely in the belly with his head. It knocked Trafton four yards backwards and out cold. That cured him. After that he just laid down after he snapped the ball!" ==Boxing==
