The Redskins have enjoyed considerable success since entering the NFL in 1932, winning five league championships and 12 division titles, and qualifying for the postseason 22 times. George Preston Marshall founded the Redskins franchise in Boston. But even an Eastern Division crown in 1936 failed to draw crowds, so Marshall moved the club to Washington, D.C., in 1937. The Redskins excelled quickly in the nation's capital, capturing two league championships and posting nine consecutive winning seasons (1937-45). Leading the team were quarterback Sammy Baugh and tailback Frankie Filchock. Between 1971 and 1992, the Redskins reached the playoffs 13 times and competed in five Super Bowls, winning three of them. Washington's stars included quarterbacks Sonny Jurgensen, Joe Theismann and Mark Rypien, wide receivers Art Monk and Charley Taylor, running back John Riggins, defensive end Dexter Manley, and safety Ken Houston. In his 12 seasons as head coach, Joe Gibbs delivered 10 winning records, eight playoff appearances and three Super Bowl championships. His first league crown, following the strike-shortened 1982 season, was secured when Washington defeated Miami 27-17 in Super Bowl XVII, led by Riggins' record-166 rushing yards. Following the 1987 season, the Redskins knocked off Denver 42-10 in Super Bowl XXII, with quarterback Doug Williams throwing for 340 yards and four touchdowns. In 1991, the 'Skins boasted an explosive offensive unit including Rypien, running back Earnest Byner and wide receivers Gary Clark and Monk. Following their 14-2 campaign, Washington handled Buffalo 37-24 in Super Bowl XXVI with Rypien throwing two TD passes. More recently, Washington qualified for the playoffs in 2005 and 2007 on the strength of running back Clinton Porter and wide receiver Santana Moss.
