The Cleveland Browns have been around for a very long time and despite their recent struggles, they’ve had some great success in their history. The Browns first started playing pro football back in 1946 with the All-America Football Conference, where they played until 1949.
Cleveland was incredibly successful during those four seasons, winning the title every year until the league folded.
From there, they joined the NFL in 1950 and their winning continued. Cleveland won four more NFL titles including their first season in the league. They won their last in 1964 and in the Super Bowl era they remain on the outside looking in.
