The Redskins in 1981. Wiki:

“Gibbs became head coach of the Washington Redskins in 1981, and went on to win three Super Bowls with a Coryell offense. Gibbs's offense featured a smash mouth running game with 3 different running backs, Hall of Famer John Riggins, George Rogers and Earnest Byner behind a massive offensive line known as the "Hogs" and a 3 receiver deep air attack featuring Hall of Famer Art Monk, Gary Clark and Ricky Sanders, known as "The Posse."

Gibbs usually kept the tight end in as an extra blocker, especially to neutralize pass rushing specialist and Hall of Fame linebacker Lawrence Taylor of the New York Giants. Today, many Coryell offenses still reduce the use of a tight end, except in the red zone.”
