Eight in the Box: Top offseason targets

Welcome to Eight in the Box, an NFL Nation feature that will appear each Friday during the offseason. This week's topic: Who should be the primary target (including trades) for each team when free agency begins?

Chicago Bears: It's unclear how much interest the Bears would have, but a tight end like Jared Cook would make sense. General manager Phil Emery is on record saying that he wants better production in the passing game from the tight-end position, and Cook is a smooth receiver. He would be a big upgrade from Kellen Davis in that regard, and new coach Marc Trestman could find plenty of different ways to line Cook up and move him around.

Detroit Lions: I'm all for the Lions pursuing running back Reggie Bush, who would provide a speedy alternative to Mikel Leshoure and also re-open a level of the passing game that has been missing without Jahvid Best. But the Lions' lack of reliable depth at safety is no less important, especially when you remember that general manager Martin Mayhew wants more playmakers in the back end. The Lions might not have the salary-cap space to sign Dashon Goldson, but fellow free agents William Moore and Glover Quin would help matters.

Green Bay Packers: Running back Steven Jackson has plenty of wear on his 29-year-old body -- nearly 2,800 touches. But a move to Green Bay would set up a satisfying conclusion to his career. The Packers will never move too far away from their pass-first philosophy, but part of that approach is the result of never having a big running back like Jackson. He could capitalize on defenses focused on Aaron Rodgers and the passing game and provide a new level of physicality to this offense.

Minnesota Vikings: There is plenty of clamor for the Vikings to make a run at speedster Mike Wallace. That's one option. From a bigger-picture perspective, a more inclusive approach would have the Vikings targeting a second-tier free agent -- such as Brandon Gibson -- re-signing Percy Harvin to a multi-year contract and focusing on a top-end speedster in the draft. Gibson has outside skills and wouldn't threaten the Vikings' salary-cap structure at the position.
