Early base downs (run package) we will see Parsons and Lve. When the team goes into the nickel, Cox is expected to replace Neal as the team's coverage linebacker, where Kearse should be also playing a similar role. Quinn did run a lot of 3 safety looks last season.
I think the biggest linebacker need heading into the offseason activities is another run down linebacker. If either Parsons or Lve go down, they could really struggle to defend the run. Cox biggest reason why he fell to the third day of the draft was due to him being a very poor run defender. Also, I think they have a specific role for him. Clark would be an ideal player for this group, but he is likely going to be a red shirt player. Player like Anthony Hitchens would be ideal, one who can be an effective two down player who comes off the field against the pass.
