Here is what it says about the Steelers:

Pittsburgh Steelers

Games missed: Guard David DeCastro (12), offensive tackle Marcus Gilbert (11), safety Troy Polamalu (9), offensive tackle Mike Adams (6), cornerback Ike Taylor (4), quarterback Ben Roethlisberger (3), linebacker LaMarr Woodley (3), wide receiver Antonio Brown (3)
Analysis: If it seems like the Steelers lose an offensive lineman or their quarterback every time they're on television, you're not alone. The offensive line finally could be a team strength this season with recent early round picks DeCastro, Adams and Gilbert returning to join center Maurkice Pouncey and guard Ramon Foster.
Pittsburgh gets knocked for fielding an aging defense, but the real problem with this strategy is that declining players are more prone to injury. Polamalu says he's in his best shape since his USC days after battling calf injuries the past two seasons. Woodley couldn't get to the quarterback after ankle and hamstring injuries early in the season. He's reportedly re-committed to having a career year. The Steelers need their two most important defenders at full strength to regain control of the AFC North.
