Here are the most interesting storylines in the AFC North:

• Second-year linebacker Lawrence Timmons was impressive in his first start of the preseason Thursday night with four tackles against the Carolina Panthers.

Morning take: We've been impressed with Timmons since we saw him blow up teammate Gary Russell during a goal-line drill in the second week of training camp. He may not start right away in the regular season, but he will make an impact.

• Cincinnati Bengals running back Rudi Johnson was miffed that he didn't play a single down in their preseason finale against the Indianapolis Colts.

Morning take: The Bengals are calling Johnson's trade reports just rumors. Yet the team is doing everything it can to suggest he's on the market.

• The Baltimore Ravens completed their preseason Thursday not knowing who their starting quarterback will be.

Morning take: Ravens head coach John Harbaugh brought up a good point that the starting quarterback is just one of 53 positions. But it is the league's most important position.

• The Cleveland Browns starters played well, but fell to 0-4 in the preseason with a 16-10 loss to the Chicago Bears.

Morning take: After a somewhat perplexing and injury-plagued preseason, it's time to finally find out if the Browns are for real. The Dallas Cowboys are up next Sept. 7.
