I think this might make Spikes more expendable actually or at least give the Bills more leverage when negotiating with him. You forget how well Bradham has played. When Kiko comes back, Bradham will slide to strong side and I could see Brown being moved to middle. I'm not saying Brown is as good of a run stuffer as Spikes because he's clearly not (at least not currently), but if he's good enough they'll have the option of going with him at middle and we'd have three backers that could play all three downs. I get excited thinking about next year's LB corps.
