 Cleveland 's success continued in the NFL in 1950 , silencing skeptics who thought the team stood out only because of the poor quality of competition in the AAFC .

Speedie had 548 receiving yards during the season and was selected for the NFL 's first @-@ ever Pro Bowl .

 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 .

 The Browns began play in 1946 , and Rymkus soon became an anchor of the team 's offensive and defensive lines . He solidified his reputation for toughness by playing more than 50 minutes per game that year despite a knee injury for which he needed surgery immediately after the season . On defense , Rymkus helped stop opponents ' rushing attacks and disrupt the opposing quarterback . On offense , he helped protect quarterback Otto Graham and opened up running room for fullback Marion Motley . Graham led the AAFC in total passing yards over its four years of existence , while Motley led the league in rushing .
