Here are the most interesting stories Friday in the AFC North:
The Baltimore Ravens' season could hinge on how much quarterback Joe Flacco improves in his second year.
Morning take: The Ravens haven’t put together back-to-back quality seasons in a long time, and a major reason was Baltimore’s quarterbacks couldn’t do the same. Flacco has a good chance to break that streak.
The Pittsburgh Steelers beat the Tennessee Titans. But they will have to move on without injured safety Troy Polamalu.
Morning take: The Pro Bowler will be out for approximately a month, and so much of what Pittsburgh does defensively is built around Polamalu’s unique skills. This is a big loss, to say the least.
The Cincinnati Bengals were given a 24-hour extension by the NFL in hopes of avoiding a blackout Sunday against the Denver Broncos.
Morning take: This could help but it still looks like it will go down to the wire to see if the Bengals can sell every ticket Friday.
Cleveland Browns coach Eric Mangini and Minnesota Vikings quarterback Brett Favre are sharing the same field once again this weekend.
Morning take: The pair led the New York Jets last year to a great start and a tumultuous finish. But the two have developed a good friendship in the process.
