Johnson played the last 3 series against us last year, I wasn't too impressed with him and I didn't think they were as dangerous with him at qb as they were with Marshall. He isn't or wasn't a threat to run the ball on the edge that Marshall or Cam were, and much easier to hem up if he drops straight back to pass. Gus has to make some adjustments to his offense because Johnson just isn't that big a running threat, when they come down the line with 3 options its pretty tough to defend, turn it up to run, hit the guy in flats almost like a pitch or throw the ball upfield to the WR if the CB comes up to cover the flat or take the run away. Thats why you have to handle their dive without the using the S, if he is checking the dive, he is late to the qb turning up or late getting to the WR as the CB has to come up. Johnson not being the runner of his other qbs, takes away one of his advantages. They run a guy in motion for speed sweep every play as well. He just tries to have more options than you can cover and does if the S is late.
