The Titans have already brought back their two starting safeties from 2011 this offseason, franchising Michael Griffin and resigning Jordan Babineaux long term. They also added a safety in the 6th round of the 2012 NFL Draft, Markelle Martin, which could end up being a steal as Martin was once seen as a 3rd or 4th round pick before an injury.
However, they don’t appear to be done adding safeties as they brought in two veteran safeties, Chris Crocker and Yeremiah Bell, for visits. They seem committed to adding depth at the position so it’s likely they sign one of them. Crocker and Bell were both cut this offseason, by the Bengals and the Dolphins respectively, but both were starters last season, albeit below average starters on the wrong side of 30.
