The Steelers had their 16th training camp practice Monday afternoon. For the second consecutive day, starting safeties Mike Mitchell and Shamarko Thomas took part in the workout.
That doesn’t sound like much, but with both players battling nagging injuries in the first three weeks of camp it was an important milestone for defensive coordinator Keith Butler as he tries to improve a unit that ranked near the bottom of the league in pass coverage in 2014.
Butler has to feel a bit like a mechanic this summer. He has had more moving parts than a car engine in his secondary.
