Georgia Institute of Technology
Georgia Tech students hold a heated, long and ongoing rivalry with the University of Georgia, known as Clean, Old-Fashioned Hate. The first known hostilities between the two institutions trace back to 1891. The University of Georgia's literary magazine proclaimed UGA's colors to be "old gold, black, and crimson". Dr. Charles H. Herty, then President of the University of Georgia, felt that old gold was too similar to yellow and that it "symbolized cowardice". After the 1893 football game against Tech, Herty removed old gold as an official color. Tech would first use old gold for their uniforms, as a proverbial slap in the face to UGA, in their first unofficial football game against Auburn in 1891. Georgia Tech's school colors would henceforth be old gold and white.
National Football League rivalries
The Immaculate Reception spawned a heated rivalry between the Raiders and Steelers, a rivalry that was at its peak during the 1970s, when both teams were among the best in the league and both were known for their hard-hitting, physical play. The teams met in the playoffs in each of the next four seasons, starting with the Raiders' 33–14 victory in the 1973 divisional playoffs. Pittsburgh used the AFC championship game victories over Oakland (24–13 at Oakland in 1974 and 16–10 at Pittsburgh in 1975) as a springboard to victories in Super Bowl IX and Super Bowl X, before the Raiders notched a 24–7 victory at home in 1976 on their way to winning Super Bowl XI. To date, the two last met in the playoffs in 1983 when the eventual Super Bowl champion Raiders, playing in Los Angeles at the time, crushed the Steelers 38–10. The rivalry has somewhat died off in the years since, mainly due to the Raiders on-field struggles since appearing in Super Bowl XXXVII.
