The 1920 Canton Bulldogs season was the franchise's sixteenth and its first in the American Professional Football Association (APFA), which became the National Football League two years later. Jim Thorpe, the APFA's president, was Canton's coach and a back who played on the team. The Bulldogs entered the season coming off a 9–0–1 performance as Ohio League champions in 1919. The team opened the season with a 48–0 victory over the Pitcairn Quakers, and finished with a 7–4–2 record, taking eighth place in the 14-team APFA. A then-record crowd of 17,000 fans watched Canton's week 12 game against Union AA of Phoenixville.

The 1920 season was Thorpe's last with the Bulldogs. Thorpe, who was of mixed American Indian ancestry, left after the season to organize and play for an all-Native American team in LaRue, Ohio. Cap Edwards replaced Thorpe as the team's coach, and Wilbur Henry, Cub Buck, Harrie Dadmun, Joe Guyon, and Pete Calac were named to the All-Pro list. Three 1920 Bulldogs players—Thorpe, Guyon and Pete Henry—were later elected to the Pro Football Hall of Fame.

Offseason Representatives of four Ohio League teams—the Bulldogs, the Cleveland Tigers, the Dayton Triangles, and the Akron Pros—called a meeting on August 20, 1920, to discuss the formation of a new league. At the meeting, they tentatively agreed on a salary cap and pledged not to sign college players or players already under contract with other teams. They also agreed on a name for the circuit: the American Professional Football Conference.PFRA Research (1980), pp. 3–4Siwoff, Zimmber & Marini (2010), pp. 352–353 They then invited other professional teams to a second meeting on September 17. At that meeting, held at Bulldogs owner Ralph Hay's Hupmobile showroom in Canton, representatives of the Rock Island Independents, the Muncie Flyers, the Decatur Staleys, the Racine Cardinals, the Massillon Tigers, the Chicago Cardinals, and the Hammond Pros agreed to join the league. Representatives of the Buffalo All-Americans and Rochester Jeffersons could not attend the meeting, but sent letters to Hay asking to be included in the league.PFRA Research (1980), p. 4 Team representatives changed the league's name slightly to the American Professional Football Association and elected officers, installing Jim Thorpe as president. Under the new league structure, teams created their schedules dynamically as the season progressed,Peterson (1997), p. 74Davis (2005), p. 59 and representatives of each team voted to determine the winner of the APFA trophy.

Standings

Game summaries Game 1: vs. Pitcairn Quakers

October 3, 1920, at Lakeside Park

The Bulldogs opened the 1920 season against the Pitcairn Quakers. The team got out to a quick lead and was never in danger, scoring 34 points in the first quarter as back Joe Guyon rushed for three touchdowns, tackle Pete Henry caught a 15-yard touchdown pass from back Tex Grigg, and back Johnny Hendren returned an interception for a touchdown. The Bulldogs were only forced to punt once in the game, and did not attempt to score in the second and third quarters because of the large lead. In the fourth quarter, however, end Bunny Corcoran caught a 35-yard touchdown pass from Guyon, and back Ike Martin ran for a one-yard touchdown. The final score was 48–0, and Guyon was the offensive star.

Game 2: vs. Toledo Maroons

October 10, 1920, at Lakeside Park

The Bulldogs were scheduled to play their second game against the Rochester Jeffersons, but faced the Toledo Maroons after that match was cancelled. For the second game in a row the Bulldogs scored over 40 points in a shutout as Martin and Guyon dominated on offense. Martin scored the first touchdown of the game with a run in the first quarter. In the second quarter, Hendren scored a rushing touchdown, and end Tom Whelan caught a touchdown pass from Grigg. In the third quarter, Martin caught a touchdown pass from Grigg, and Grigg rushed for another. The Bulldogs' final score was a rushing touchdown from back Pete Calac in the fourth quarter.

Game 3: vs. Cleveland Tigers

October 17, 1920, at Lakeside Park

The Bulldogs next faced the Cleveland Tigers, their first APFA opponent, and won 7–0 before a crowd of 7,000 people.

Thorpe made his season debut in the game, coming in as a substitute in the fourth quarter.

Game 4: at Dayton Triangles

October 24, 1920, at Triangle Park

Bulldogs battled the Dayton Triangles in week five. The Bulldogs opened the scoring in the first quarter on a two-yard rushing touchdown by Pete Calac. But the Triangles came back in the second quarter, scoring twice: back Frank Bacon had a four-yard rushing touchdown, and end Dave Reese had a 50-yard receiving touchdown. Guyon scored a 22-yard rushing touchdown during the corner, but the extra point sailed wide. In the third quarter, the Triangles responded with a 3-yard rushing touchdown by back Lou Partlow, but Dayton missed the extra point to make the score 20–14. Thorpe then came into the game, and kicked a 45-yard field goal to bring his team within three points. In the final minutes, Thorpe kicked another 35-yard field goal to tie it. The Triangles were the first team to score on the Bulldogs since the opening game of the previous year.

Game 5: vs. Akron Pros

October 31, 1920, at Lakeside Park

The Bulldogs' next opponent was the Akron Pros, who were undefeated at the time and were gaining attention around the league.Carroll (1982), p. 2 The game was the first of a two-game series between the Bulldogs and Pros, considered to be two of the best teams in the country. In the first quarter, after an exchange of punts, Pros tackle Charlie Copley kicked a 38-yard field goal. On a Bulldog possession at midfield, a Gilroy pass was tipped by the Pros' Copley and Bob Nash. Pros tackle Pike Johnson caught the ball before it landed and ran 55 yards for a touchdown. In the third quarter, Jim Thorpe came into the game but could not get the Bulldogs back into the game.

Game 6: at Cleveland Tigers

November 7, 1920, at Dunn Field

Coming off their first loss, the Bulldogs faced the Cleveland Tigers in week seven. Neither team scored in the first quarter, but the Bulldogs ran for two touchdowns in the second.

Game 7: vs. Chicago Tigers

Game 8: at Buffalo All-Americans

November 21, 1920, at Buffalo Baseball Park

In week nine, the Bulldogs played the Buffalo All-Americans, who were undefeated at the time. Thorpe started the game but came out at halftime because he believed it would end in a tie.

The game was the only loss of the season for the All-Americans.

Game 9: at Akron Pros

November 25, 1920, at League Park

In week ten, the Bulldogs played the Pros for the second time in the season. In the first quarter, a fumbled punt by the Bulldogs gave the Pros the ball at their 32-yard line.
