I'm assuming that Trevathan's days are numbered as he ages. He's been out a lot with injury. This might be his last year in Chicago, as the window opens for the team, so it'll be Smith and ________ in the middle. Kwitkowski will have to step up to stay, and this new ILB will push him at both ILB and on special teams. Either Kwit will take the next step, or the new guy will grow into it, or we will be drafting another ILB soon.
