Washington is third with an average of 84 yards per game while Booker is ninth at 71.5 yards per game.
The last time FSU had two backs average 70-plus yards per game on the ground was 1984 with Greg Allen (107.9 yards per game) and Roosevelt Snipes (75.6).
Booker, the Seminoles' leading rusher with 786 yards, and Washington currently rank as one of the most productive sets of rushers in the Bobby Bowden era.
The duo is on pace to rush for 1,698 yards this season, a mark that would put them fourth among running back tandems at FSU since Bowden took over in 1976 behind Sammie Smith and Dexter Carter (1,909 total) in 1987, Allen-Snipes (1,763) in 1983 and Allen-Snipes (1,727) again in 1984.
The Mountaineers also have a pair that falls into the 70-plus rushing yards per game category in running back Kay-Jay Harris (82.5) and quarterback Rasheed Marshall (71.8)
