Saints run defense

They're a genuinely good run defense. But with Rankins out and the need to try and keep Brees and Co. off the field the Rams have to run the ball more. Regardless of if they are getting 7.0 YPC or 3.0 YPC they have to have 25+ rush attempts in this game in my opinion. If the Rams RBs have 13 attempts they will lose the game.
