I'm not sure someone other than Nick Perry can play up to the LOS and be that 5th linebacker. Granted, the front 7 is supposed to be beast this year, but on option plays, there needs to be a safety who can cover the sideline and make sure no big plays can happen. I don't know much about Jarrick Williams being that guy other than I know he has some experience, but he doesn't seem like that kind of guy that Vinnie was or Barron. Need someone to be that 5th linebacker.
