PITTSBURGH (AP) – Pittsburgh Steelers general manager Kevin Colbert says there’s work to be done if the team wants to bring back quarterback Ben Roethlisberger next season. Roethlisberger and the team have talked about reducing the veteran’s NFL-high $41 million salary-cap hit. Colbert pointed to a lowering of the salary cap and a roster in transition as significant obstacles to navigate if Roethlisberger wants to play an 18th season in Pittsburgh.
