Miami's Larry Csonka and Mercury Morris formed the first running back duo to rush for 1,000 yards each in 1972. Franco Harris and Rocky Bleier did it for Pittsburgh in 1976 and Earnest Byner and Kevin Mack did it for Cleveland in 1985.
Atlanta also had two 1,000-yard rushers in 2006 with running back Warrick Dunn and quarterback Michael Vick.
