In their inaugural AFPA season, the Pros posted an undefeated, 8–0–3 season. As a result, they were the first team in the history to complete a non-modern "perfect season". Only four other teams has accomplished this feat: the 1922 Canton Bulldogs at 10–0–2, the 1923 Canton Bulldogs at 11–0–1, the 1929 Green Bay Packers at 12–0–1, and the 1972 Miami Dolphins at 17–0. Prior to 1972, the NFL did not count ties into winning percentage; however, in that year the NFL retrospectively altered its standings to treat tied games as being worth half of a win. With that being said, the 1972 Miami Dolphins are the only team to have a modern perfect season. Three other teams accumulated a perfect regular season record, but lost in the post season. The 1934 Chicago Bears posted a 13–0 record but lost in the 1934 NFL Championship Game to the New York Giants. The 1942 Chicago Bears posted an 11–0 record but lost in the 1942 NFL Championship Game to the Washington Redskins. Lastly, the 2007 New England Patriots posted a 16–0 record but lost in Super Bowl XLII to the New York Giants.
