Both the Raiders and Broncos were 4-0 when they clashed in Oakland Coliseum on October 16, 1977. On that day, Broncomania was born. Denver overwhelmed Raider QB Ken Stabler, pressing him into seven interceptions (one shy of the NFL single-game record). That, coupled with a fake field goal attempt turned touchdown, lifted Denver to a 30-7 win, making the Broncos true contenders.
