New to the team: Sean Jones
All but one of the safeties currently on the roster was with the Detroit Lions last season. At the top of the depth chart, both starters from last season are back, although there are question marks about injuries surrounding both of them. Louis Delmas had his 2011 season derailed by injuries, and injuries are a concern going forward considering how often he is banged up. The same sort of goes for Amari Spievey, who spent a good part of the offseason recovering from a concussion.
There has been some talk that Spievey's starting job may be in jeopardy due to the combination of his inconsistent play and tough offseason. If somebody were to step in and replace Spievey in the starting lineup, it would likely be Erik Coleman or Sean Jones. Coleman had his 2011 season cut short early on due to an injury, but he re-signed with the Lions this offseason in hopes of getting to see the field more this year. Jones just recently signed and will be battling Coleman for a roster spot and potentially Spievey for a starting job.
The other safeties on the roster are John Wendling, Don Carey and Ricardo Silva. Wendling is expected to make the 53-man roster again as a special teams player. I know many fans view him as a waste of a roster spot, but the Lions value his contributions on special teams. As for the other two safeties, Carey converted to this position from cornerback this offseason in hopes of improving his chances of making the team, and Silva spent most of last season on the practice squad. Their chances of making the roster seem slim right now.
Need going forward?
The Lions could probably use an upgrade in the depth department at safety, and they spent a good part of the offseason pursuing a veteran free agent at this position. In the end, they settled on signing Jones, so unless a trade comes along or somebody worth signing gets released by another team, it seems like the Lions are set. They could always add a camp body, but it doesn't seem likely right now that anybody who could compete for a starting job will be added during camp.
