Frank Ryan
Ryan took over as Cleveland’s quarterback in 1962 after an underwhelming start to his career with the Rams. In five seasons as the Browns’ primary starting QB, he led the team to a 48-17-1 record. That 5-year peak (1963-1967) saw Ryan throw more TD passes than anyone except Hall of Famer Len Dawson
Ryan made three Pro Bowls and finished in the league’s top 10 in passing yards and top five in touchdowns four times each. He lacks the career longevity of most Hall-worthy QBs, but his peak stacks up as well, and in many cases better than several who are enshrined in Canton.
