I think the LB's will surprise some people. I think a lot was based on McClain. Though many never liked him, he did make a difference at times, and other times he didn't. But he was more good than mediocre. But the same people that said he wasn't realy all that good, are the same ones saying the LB's now suck.
Hitchens played very well in place of McClain, so there is no reason why he shouldn't be bad now, that just doesn't make sense. He will be fine. Also he has Lee out there with him, as before in 2014 he didn't. Nzeocha has looked good, and we have Durant back also. When he when out with an injury in 2014, that hurt the defense more so than when McClain wasn't in there.
Now we need to see if Wilson is the player they hoped he would be when they drafted him. Wilber can be serviceable, as the coaches seem to like him, and his versatility. And he can line up at DE if needed. Even though I often posted why is he here. But they know better than I do.
That leaves the staus of a 7th LB. Gachkar, but is he back, I have not heard anything on him, just that he had a broken thumb. He too can be serviceable and like Wilber both are ST's aces.
I can see Morris slipping in there too, but a few plays in PS games doesn't warrant a roster spot yet IMO.
If the DT's do what we hope they can do, this allows the LB's do what they are supposed to do better. It's that domino effect.
