The 1950Cleveland Browns season was the team's first season with the National Football League after playing the previous four years in the All-America Football Conference, which folded after the 1949 season. The Browns' first NFL game was against the two-time defending champion Philadelphia Eagles. The overwhelming consensus at the time was that the Eagles would blow the Browns off the field; there were still many who thought the Browns were merely the dominant team in a minor league. However, the Browns were determined to prove they belonged. They shredded the Eagles' vaunted defense for 487 yards of total offense en route to a 35–10 blowout.
Behind a potent offense that included future Hall of FamersOtto Graham, Marion Motley and Dante Lavelli, the Browns picked up right where they left off in the AAFC. After going 10–2 in the regular season, the Browns defeated the New York Giants 8–3 in a playoff game and then beat Cleveland's previous NFL tenants, the Rams (who were now in Los Angeles), 30–28, in the NFL Championship game. Since the NFL does not recognize the AAFC's records, this technically makes the Browns the most successful expansion team in league history. However, the 1950 Browns were not an expansion team in any sense of the term.
The Browns had been the AAFC's most dominant team, winning all four of its championships. The Rams, who left Cleveland after the 1945 season for Los Angeles, were making their second straight appearance in an NFL title game.
