Robert Griffin III suffered a dislocated ankle against the Jacksonville Jaguars, which opened the door for Cousins to come in and show his stuff. He was impressive in the stat sheets, throwing for 250 yards with two touchdowns and no interceptions, and an upcoming matchup against the Philadelphia Eagles is favorable. With Griffin III down, Cousins becomes a viable option off the waiver wire for Week 3.
