Otto Graham: Otto Everett Graham Jr. (December 6, 1921 – December 17, 2003) was an American football quarterback who played for the Cleveland Browns in the All-America Football Conference (AAFC) and National Football League (NFL).  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.  With Graham at quarterback, the Browns posted a record of 114 wins, 20 losses, and four ties, including a 9–3 win–loss record in the playoffs.

He is also known for being one of only two people (the other being Gene Conley) to win championships in two of the four major North American sports—1946 NBL (became NBA) and AAFC championship, plus three more AAFC and three NFL championships.
