1920 Buffalo All-Americans season

The 1920 Buffalo All-Americans season was the franchise's inaugural season with the American Professional Football Association (APFA), an American football league, and fifth total as a team. The All-Americans entered 1920 coming off a 9–1–1 record in 1919 as the Buffalo Prospects in the New York Pro Football League (NYPFL). Several representatives from another professional football league, the Ohio League, wanted to form a new national league, and thus the APFA was created.

Buffalo reshaped itself for the 1920 season. Only two players from the 1919 season stayed, and the team went into new management. Tommy Hughitt (one of the returning players) became the new coach, and Frank McNeil became the new owner. The All-Americans opened the season with a 32–6 victory over the local semi-pro team West Buffalo, en route to a 9-win, 1–loss, 1-tie (9–1–1) record. Its only loss of the season was a 3–0 game against the Canton Bulldogs. A meeting was held by the officials of the APFA to determine a winner, with each coach having a vote. The All-Americans stated their cases; they believed they should deserve the championship trophy because they had the most wins and were undefeated against the Akron Pros and the Decatur Staleys. The officials, however, awarded the Brunswick-Balke Collender Cup to the Akron Pros because they had a 1.000 winning percentage. Had standings been counted as they are as of today, the All-Americans would be co-champions.

The sportswriter Bruce Copeland compiled the 1920 All-Pro list, but no players from the All-Americans were on it. That is because Copeland wrote for the Rock Island Argus and did not see any players from the easternmost teams in the league. As of 2012, no player from the 1920 All-Americans has been enshrined in the Pro Football Hall of Fame.
