The bitter rivalry that existed between these two teams began in 1950 when the All-American Football Conference folded and three of the AAFC teams entered the NFL. The 49ers and Colts were joined by a Browns’ team that had won all four of the AAFC championships under head coach Paul Brown.
Against the Steelers, the Browns own a 39-28-1 record in Cleveland, built primarily in the early years when they dominated the Same Old Steelers who struggled to put up any resistance.
With Otto Graham at quarterback, the Browns monopolized the NFL Eastern Division in the early part of the fifties.
