Redskins plan to 'spy' Cardinals' David Johnson with rookie Su'a Cravens, per source

Facing one of the NFL's best running backs in Arizona's David Johnson, the Redskins plan to use rookie linebacker Su'a Cravens as a spy in nickel coverage to slow down the Cardinals' threat, per a source close to the team. Johnson ranks third in the NFL with 921 rushing yards, but it's the variety of ways the Arizona offense uses their second-year running back that makes him so difficult to handle for opposing defenses. Cravens comes into the game with momentum as perhaps the Redskins most dynamic defensive threat.
