Graham is regarded by critics as one of the most dominant players of his era, having taken the Browns to league championship games every year between 1946 and 1955, winning seven of them.

A system quarterback is an American football quarterback who flourishes under a particular offensive system, specifically one that focuses on passing.  The term is often seen as a pejorative, for it implicitly downplays a quarterback's talent or skill by implying that a successful offense is due to a particular scheme or that a quarterback is successful due to his employment under specific circumstances.
