CC Brown has looked very good so far. His coverage skills have improved and he looks solid in run support, although that is a little hard to tell without full tackling. I've heard CC has been working very hard, and from the looks of it so far I'm lead to believe that. Earl has looked ok, but I haven't really noticed him much on most plays, which is generally a good thing for DBs. It seems as though he's the deep cover guy so he hasn't been involved in a whole lot of plays yet, but he's looked fairly solid. Ramon Walker has mainly played on the 3rd team and I don't see him making the team, I think Simmons and Michael Stone will probably be the backup safeties. John Walker has had a lot of rookie mistakes but he seems to be improving and learning well from Hoke, and he has pretty good size and athleticism. I think he could definitely make the active roster depending on whether they bring in any more vets, and if they do I think they'll at least keep him on practice squad.
