20. Ben Roethlisberger
In one of the most confusing career arcs in NFL history, Ben Roethlisberger has gone from phenomenal to terrible and then back to phenomenal over the course of his 12 seasons. With two Super Bowl titles and the chance for one or two more before he hangs it up, Roethlisberger and Pittsburgh’s success over the next 2-3 years will determine whether he moves higher up this list. Arguably the best quarterback at extending plays and improvising in NFL history, Roethlisberger’s deceptive agility and incredible arm strength ensure a spot in Canton.

19. Otto Graham
Dominating during an era that is often forgotten in the confines of NFL history, Otto Graham and the Cleveland Browns couldn’t be stopped from 1946-1955. Reaching the league championship every year in that span, Graham was the biggest reason why. He holds the record for highest win percentage of any starting quarterback in NFL history (0.814), with Cleveland finishing 114-20-4 in games started by Graham. As an efficient passer and the ultimate winner, Graham would have gained even more notoriety had he played during the Super Bowl era.
