Morning take: Ravens' Harper making plays

Posted by ESPN.com's James Walker

Here are the most interesting stories Tuesday in the AFC North:

Morning take: The Ravens will need someone to step up in a reserve role at receiver. I'm curious to see whether it's Harper or another backup receiver who performs best in the preseason.

  • Does new Cleveland Browns coach Eric Mangini need to loosen up?

Morning take: The Browns coach has undoubtedly changed the culture in Cleveland with his disciplinarian style. But the only true litmus test is whether this translates into more or less victories by season's end.

Morning take: The Bengals went from a team without pressure to suddenly having high expectations. Can they handle the difference?

  • Instinctive plays are part of what separates Pittsburgh Steelers safety Troy Polamalu.

Morning take: Polamalu always has a nose for the football and making the key play. It's something you can't teach and is ingrained in many of the league's greats.
