Although Gibbs helped craft a passing-oriented attack during his time in San Diego, his Redskins teams incorporated a smash-mouth, rushing-oriented attack called the counter trey. By building a strong offensive line (known as "The Hogs") Gibbs was able to control the line of scrimmage, allowing workhorse running backs John Riggins, George Rogers, and Earnest Byner to power the ground game. Gibbs added a deep passing attack which complemented the ground game, utilizing agile receivers such as Art Monk, Gary Clark, and Ricky Sanders. Gibbs' offense was aided by aggressive defensive units under the direction of defensive coordinator Richie Petitbon.
