I read a story that said they were adjusting the defense to help more in the running game and I assume that means using zone defense to protect themselves so the d-backs don't get beat easily with man to man coverages by helping to defense the run. I don't know really what all that means to be honest. Are they afraid of leaving themselves open if the d-backs play closer to the line to support the fun defense? Man to man might not be as effective? I don't know. I'd be more worried about the speed of Marshall and others of covering man to man than I would be of the D-backs. Maybe I didn't read the same story as you.
