For as much hang-wringing as there might be about the cornerback position right now for the Pittsburgh Steelers, I think that the one position most up in the air in the secondary right now is that of the strong safety, where the team continues to look for the replacement for Troy Polamalu.
Of course, the plan was for that to be Shamarko Thomas, who trained with Polamalu during the 2014 offseason leading up to the start of the future Hall of Famer’s final season with the team before he retired. The third-year safety spent all of the offseason—minus a brief training camp injury—all the way through the conclusion of the preseason before the coaching staff made the determination that he wasn’t ready to start.
