A look at the free-agent priorities for each NFC North team:
Assemble a starting offensive line: As we've noted many times, the Bears have held off any public discussion about their five linemen pending the results of free agency. Well, we're here. It's time for the dominoes to start falling. The first will be whether center Olin Kreutz re-signs. It's generally expected, but nothing is guaranteed. Then, the Bears need to decide whether to pursue any starting-caliber guards or tackles. You would think they'll seek at least one new starter. Will they raid the Atlanta Falcons' glut of linemen? Might they take a flier on Robert Gallery? We'll know soon enough.
Establish a strongside linebacker: The position has largely been held by Pisa Tinoisamoa and Nick Roach over the past two years, but both have expiring contracts. It makes sense to re-sign at least one given the lack of offseason work for a presumptive new starter, and Roach is the younger of the two. If the Bears have another player on the roster they've targeted for this job, it's not readily apparent. While they're at it, the Bears should seek depth at defensive tackle following the release of Tommie Harris. They did draft Stephen Paea, but the Bears might pursue Seattle Seahawks free agent Brandon Mebane, as well.
Sift through receivers: From a media perspective, at least, there has been more offseason talk than ever suggesting the Bears will/should/might pursue a free-agent receiver. This year's class is deep, from Sidney Rice to Santonio Holmes to Randy Moss, and a number of other veterans could be available via trade. Coach Lovie Smith has said he wouldn't mind a receiver bigger than his current trio of sub 6-footers, and Devin Hester has lobbied publicly to sign Santana Moss. I think the increased discussion is largely a product of lockout boredom, but it wouldn't hurt the Bears to add depth so that Hester can be used more efficiently.
Sign a starting cornerback: The Lions' top cornerbacks under contract are Alphonso Smith and Nate Vasher. Chris Houston, who started 15 games last season, is a free agent, so it's possible the Lions will bring Houston back. Or they could seek an outside upgrade, be it Nnamdi Asomugha or Ike Taylor or Johnathan Joseph. Lions Fever would spike if they can land Asomugha, but they would have to use most of their salary-cap space to do it. For several reasons, the odds are against it.
Sort out the linebacker position: DeAndre Levy is the only linebacker assured a 2011 starting job, but even Levy can't be totally sure if he will play outside or in the middle. That answer will come only after the Lions sift through the available free agents. They could pursue one with a background in the middle, perhaps Stephen Tulloch. Or they could seek an outside linebacker to replace the released Julian Peterson. One of their outside positions is likely to be decided by a training camp competition among incumbents.
Evaluate right tackles: Early indications have been that Gosder Cherilus has made progress from microfracture surgery on his knee. If there is any question, however, the Lions might want to bolster their depth. Corey Hilliard did a decent job as Cherilus' replacement late last season. But keeping quarterback Matthew Stafford healthy is at a premium this season. Do the Lions want to face the possibility of opening the year with a backup plan at right tackle?
Stay the course: It's been well-documented that general manager Ted Thompson hasn't participated much in free agency over the past few years, and it's hard to imagine his changing tack dramatically this summer. Thompson's most important decisions will be deciding which of his pending free agents to re-sign and which ones he should allow to depart.
Re-sign place-kicker Mason Crosby: Thompson gave Crosby a second-round tender in February in the event Crosby wound up as a restricted free agent. That move suggested Crosby is in the Packers' future plans and makes re-signing him one of the first orders of business now that he is an unrestricted free agent. Crosby has had some difficulties over the years, but kicking in Green Bay is difficult given the weather and he has made some important adjustments. Concerns about his kickoffs should be minimized by the NFL's decision to move them up 5 yards.
Think twice: The Packers appear set to let defensive end Cullen Jenkins depart. They can do so knowing they have a number of intriguing young players to compete for that job, from Mike Neal to C.J. Wilson to Jarius Wynn. But another player the Packers might lose, Daryn Colledge, doesn't have an obvious replacement. Would the Packers shift T.J. Lang from backup tackle to guard? Would first-round draft pick Derek Sherrod, their projected left tackle of the future, get a crash course on step down? It's something to think about and, given the lack of an offseason, might spur further discussion about re-signing Colledge.
Address receivers: Are the Vikings about to bid farewell to receiver Sidney Rice, a 24-year-old who is one year removed from an 83-catch Pro Bowl season? There is nothing they can do to stop it at this point, and Rice seems intent on at least testing his value on the open market. The Vikings spent most of last season searching for a suitable replacement when Rice was injured, and that job will intensify this summer. They have added an additional pass-catching threat in rookie tight end Kyle Rudolph. But if they lose Rice, the Vikings must either sign or trade for an established veteran to join Percy Harvin and Bernard Berrian (if he makes the team).
Find a kicker: The Vikings made no known effort before the lockout to re-sign veteran Ryan Longwell, who has converted 43 of 46 kicks over the past two seasons. It's possible they'll make their move now. But they did not draft a kicker, and if Longwell signs elsewhere, the Vikings will have to scour the always-murky free-agent market. I'm guessing they already have a plan on this issue, but we haven't smoked it out yet.
Establish QB depth: We all know that rookie Christian Ponder eventually will assume the starting job. But are the Vikings comfortable with Joe Webb and Rhett Bomar as their only alternatives if Ponder needs some development time? I'm not sure about that. I also wonder if making Webb the No. 2 quarterback would limit his opportunities to contribute in other ways, perhaps as a receiver or a kick returner. For that reason, it would make sense for the Vikings to seek a quarterback with more experience to pair with Ponder.
