by - Milt Plum
We are going way back for this one. Milt Plum came to the Browns in 1957 and was tasked at replacing the legend that was Otto Graham. Plum was part of the Browns offense that was built around Jim Brown and Tommy O’Connell at the time. Plum’s passer rating of 110.4 in 1960 season was the best single-season mark until 1989.
He played for the Browns between 1957-1961 while reaching the Pro Bowl twice. Plum would finish with 8,914 yards and 66 touchdowns while going 33-16-2 as a starter before being dealt to the Lions after the 1961 season.
It has to be Otto Graham.
