Here are the most interesting story lines in the AFC North:
Morning take: The Steelers came into the season with the NFL's toughest schedule, yet enter the bye week at 4-1. It wasn't always pretty, but the results were effective.
Morning take: That mystery writer also was impressed with the depth Pittsburgh has shown the past two weeks, which will serve the Steelers well later in the year.
Morning take: In fact, we noticed a pair of shoddily officiated games this weekend involving AFC North teams, with the other being the Steelers-Jaguars contest. The worst part of this particular call was it came at a crucial time of the game.
Morning take: Only if Cincinnati builds on Sunday's solid showing. If the Bengals lay an egg next week and fall to 0-6, everyone will quickly forget how well the team competed Sunday against one of the NFL's best.
