Led by quarterback Otto Graham, fullback Marion Motley and ends Dante Lavelli and Mac Speedie, the Browns won the AAFC championship in 1949, their fourth straight title. The AAFC folded after the season, and the Browns were absorbed by the more established National Football League (NFL). The team finished the 1950 season with a 10–2 record and won the NFL championship by beating the Los Angeles Rams. The Browns reached the NFL championship each year between 1951 and 1953, but lost once to the Rams and twice to the Detroit Lions.
