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.
