Robert Griffin III has said that running back Alfred Morris is the Washington Redskins' biggest offensive weapon.
The NFC East side have added former Philadelphia Eagles running back DeSean Jackson to their roster this off-season to increase their rushing options.
However, the quarterback told the team's website: "I think everyone would lean towards DeSean or Pierre [Garcon] or Jordan Reed, I think it's Alfred.
"With him, defenses have to make a decision whether to put guys in the box to stop him or leave the box light and allow Alfred to go between the tackles and lure in the safeties. I think it will be interesting to see what defenses do against him."
In his two seasons with the Redskins, Morris has recorded 2,888 rushing yards and scored 20 touchdowns.
