I think Lewis's shoulder was messed up all year, still though, he needs to be playing the 3rd safety in sub sets.
Not the starter.
Which is why, being a passing league, I'd like to target Byrd as our big free agent signing this offseason. We likely won't though.
All these spots don't have to be filled int he draft, free agency is a good place to get depth and an occasional starter but you have to pay for it.
