Robert Griffin III says his knee is fine, and he'll run if it's needed to spark the 0-2 Redskins

Washington Redskins quarterback Robert Griffin III insisted Wednesday his knee is fine, brushing off questions about his health from outside observers and remarks this week from his top wide receiver, who said a knee brace and lack of preseason playing time were affecting Griffin's performance. Griffin also declared he is willing and able to run the ball as often as necessary to spark his 0-2 team.
