Haynesworth could go awry at any time. Mike Wright's concussion situation could go awry at any time. The rest of the DL have a variety of durability/reliability issues, as football players commonly do -- not necessarily worse than average, as a group, but not better either. So what's the minimum number of DL it will make sense to keep, assuming both Hayneworth and Wright are included? Edit: I'm excluding guys whose only claim to being a DL is outside rushing on passing downs. Generally they're OLBs, but if some guy of that kind isn't really an OLB -- well, I'm still excluding him.
