Darby and Ragland weren't scheme fits, and the last FO tried to persuade us that supposedly only they were smart enough to know Seymour would be an All Pro once he had his vision fixed. These are washes IMO.
Sammy, when healthy, is a huge loss. He was MIA most of last season, however, and he's a luxury until you have a playoff contender with a QB in place. Nothing is drastically different from last season, IMO. I melted down after the Sammy trade, but now I'm back to being interested in seeing what this looks like when the games mean something.
