 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 .

The Browns have never played in a Super Bowl . Former owner Art Modell 's relocation of the Browns after the 1995 season ( to Baltimore creating the Ravens ) , caused tremendous heartbreak and resentment among local fans . Cleveland mayor , Michael R. White , worked with the NFL and Commissioner Paul Tagliabue to bring back the Browns beginning in 1999 season , retaining all team history .
