 In winning all of their regular season games and the AAFC championship, the Browns recorded the first perfect season in professional football since the advent of NFL championships in 1933. The feat has been duplicated only once since, by the Miami Dolphins in 1972. When the AAFC faltered and dissolved after the 1949 season and the NFL absorbed the Browns, their new league did not recognize AAFC statistics, including the perfect season. The Pro Football Hall of Fame, however, recognizes it as a perfect season. In 2008, United States Senator Sherrod Brown, who represents Ohio in the United States Congress, sent a letter to NFL commissioner Roger Goodell asking the league to recognize AAFC championships and team records including the perfect season. At the time, the New England Patriots were undefeated as they prepared for the Super Bowl against the New York Giants, a game they went on to lose. Dante Lavelli also advocated for the NFL to adopt AAFC records.
