History and League Success
The team was a 1960 charter member of the American Football League. The team is named for a former football team of the same name that played during the late 1940's in the defunct All-American Football Conference, which itself was named for a popular barbershop quartet, which itself was named for William Frederick Cody, more famously known as Buffalo Bill.
During its run in the AFL it won two league titles (1964 and 1965) but afterwards were relatively unsuccessful. During the 1970's the team's most famous player, O.J. Simpson, would become the first NFL player to rush for 2,000 or more yards in a single season. It also was the only team to ever play a team from the Canadian Football League (the Hamilton Tiger-Cats; Hamilton is located within driving distance of Buffalo); unfortunately they also have the dubious distinction of being the only NFL franchise (though part of the AFL at the time) to lose to a CFL team (21-38 on August 8, 1961).
The teams best period of success was from 1991-1994 when they reached the Super Bowl for four straight years, only to lose each time. The four consecutive appearances is an NFL record; the four losses ties them with the Minnesota Vikings for most losses by a team that has not won a Super Bowl (the consecutive losses is itself an NFL record as well).
