Morning take: Harbaugh addresses Marshall

Posted by ESPN.com's James Walker

Here are the most interesting stories in the AFC North:

Morning take: Every time a receiver becomes available, the Ravens seem to flock to the top of the list. Terrell Owens didn't land in the Ravens' nest. Neither did Anquan Boldin. Will Marshall make it 0 for 3?

Morning take: There are high hopes for the Bengals' defense in 2009, which didn't get much help from the offense and still was rated No. 12 in the NFL. It will be interesting to see what their defense can do with some points on the board.

Morning take: Hood says he got better every day during the offseason, which is a good sign for the defending champs.

Morning take: To no surprise, Costanza is familiar with Browns coach Eric Mangini when he signed with the New York Jets in 2006.
