Let's see what is in the AFC North inbox.
James Walker: That's a legitimate concern, RJ, because there is a history of injuries with both players. Boldin hasn't played in all 16 games since 2006, and Stallworth hasn't played a 16-game season since 2007. Boldin's situation is obviously a bigger concern because he is a starter and is expected to play a major role in the offense. Boldin did play in 15 games last year for the Arizona Cardinals, so maybe that's a good sign. But there's no way to forecast injuries.
Sean McMann from Pittsburgh writes: With the Cincinnati Bengals having added new WR depth to their team, which receivers do you them cutting?
Walker: It's definitely going to be a numbers game in Cincinnati, Sean. Although any injury could change things, I would say Chad Ochocinco, Antonio Bryant, Andre Caldwell and third-round pick Jordan Shipley are locks. So that's four roster spots taken, and it probably leaves two (possibly three) spots left on the 53-man roster. My two picks from there would be Matt Jones and a possible toss-up between Quan Cosby and Jerome Simpson. But I reserve to right to alter the list once I see these players compete in minicamps and training camp.
Cory writes: How do the Steelers go about their offseason preparation at the quarterback position? How are they splitting up the reps considering Ben Roethlisberger's suspension?
Walker: I get e-mails from Steeler Nation saying it's tired of "Big Ben." Then I get questions from Steeler Nation about the quarterbacks. Which one is it? Byron Leftwich is the favorite to win the job, Cory, because he's been getting all of the first-team reps. It looks like Dennis Dixon has to make up some ground this summer to have a chance. But Pittsburgh's coaching staff likes Leftwich's steadiness and the experience he brings to the offense.
Joseph from Columbus, Ohio, wants to know if any of the Cleveland Browns' young receivers will have a breakout year?
Walker: I'm not prepared to answer that question, Joseph. I have a lot of questions about this group and I need to see more practices and camps. I can say that second-year receiver Brian Robiskie looked good in the first week of organized team activities. He made several nice catches, and the Browns could really benefit from that. But I'm not sure Mohamed Massaquoi is ready to be a No. 1 receiver, and the team may still look to add a veteran. So it's too early to say.
