 The rivalry cooled down in the 1980s after the Colts struggled and moved to Indianapolis, but heated up once again in the late 90s until the Colts were reassigned into the AFC South as a result of the 2002 realignment of the NFL's divisions.The Dolphins also share historic rivalries with the Las Vegas Raiders, Los Angeles Chargers, and Pittsburgh Steelers, stemming from often competing against these teams in the playoffs during the Don Shula era.The Dolphins originally played all home games in the Orange Bowl in Miami.
