A look at whether each NFC North team has been a winner or a loser in free agency.

Chicago Bears: A hot start in free agency netted left tackle Jermon Bushrod and tight end Martellus Bennett. The Bears had been trying for five years to find a genuine left tackle, and Bushrod's arrival should boost the faith of quarterback Jay Cutler. Bennett, meanwhile, gives the Bears the kind of pass-catching tight end they once had in Greg Olsen. But Bushrod and Bennett accounted for most of the salary-cap space the Bears had budgeted to use, and now they are nibbling the edges. Overall, however, the Bears improved two important positions, making them winners in free agency.

Detroit Lions: The NFC North's most active offseason team has added three new starters in running back Reggie Bush, defensive end Jason Jones and safety Glover Quin. Bush will have a big impact on balancing the explosiveness in the Lions' offense, and Quin will pair with the returning Louis Delmas to give the Lions their best safety duo in recent memory. The Lions have improved as many positions as they could have given their tight salary-cap situation.

Green Bay Packers: It's difficult to win when you don't play, and general manager Ted Thompson is notoriously reluctant to compete financially in the market. He allowed receiver Greg Jennings to sign with the Minnesota Vikings and didn't make a good enough offer on running back Steven Jackson. But the Packers have made the playoffs in four consecutive seasons by following a similar approach. These days, their focus is on saving enough salary-cap space to re-sign quarterback Aaron Rodgers and linebacker Clay Matthews. The Packers won't find two players better than that on the free-agent market.

Minnesota Vikings: In essence, the Vikings traded receiver Percy Harvin for Jennings, along with a first-, third- and seventh-round draft pick. They won't replace Harvin's unique skill set, but that's not a bad recovery. The Vikings are also in a better spot at backup quarterback with Matt Cassel rather than Joe Webb. But they don't have a middle linebacker after bidding farewell to Jasper Brinkley, and they remain thin at cornerback after releasing Antoine Winfield. The Vikings remain a work in progress this offseason. They haven't won or lost yet.
