Backup: Bruce Gradkowski

Best-case scenario: The Steelers' offensive line bounces back from its group-wide epic fail last year, and Big Ben stays upright long enough to make full use of his unknown but solid skill position corps (Emmanuel Sanders, Antonio Brown, Le'Veon Bell) and lead Pittsburgh to a wild card berth.
Worst-case scenario: Big Ben likes to scramble-just not this much. His O-line develops more holes than a particularly porous strain of Swiss cheese, and Roethlisberger gets chased around all season like the piece of shit human being he is.
