ChicagoBears.com takes a look at how the Bears' division rivals have fared in the first 10 days of the 2016 free agency period.
Free agent arrivals: Safety Rafael Bush (Saints), receiver Marvin Jones (Bengals), defensive tackle Stefan Charles (Bills), defensive back Tavon Wilson (Patriots), cornerback Johnson Bademosi (Browns).
Free agent departures: Safety Isa Abdul-Quddus (Dolphins), linebacker Travis Lewis (Vikings).
Notable re-signed players: Defensive tackle Haloti Ngata, outside linebacker Tahir Whitehead, quarterback Dan Orlovsky.
Summary: With the retirement of receiver Calvin Johnson, the Lions made adding a player at that position a top priority. Enter Jones, who will be an immediate starter after signing a five-year contract with Detroit. Only 26, he should see a bump in production after catching 65 passes a season ago in Cincinnati. The Lions also looked to upgrade their secondary after allowing 7.17 yards per pass play, one of the highest averages in the NFL in 2015. Bademosi is a special-teams ace that should help on kickoff and punt coverage units.
Green Bay Packers
Free agent arrivals: None.
Free agent departures: Cornerback Casey Heyward (Chargers), quarterback Scott Tolzein (Colts).
Notable re-signed players: Placekicker Mason Crosby, nose tackle Letroy Guion, linebacker Nick Perry.
Summary: The Packers are generally quiet in free agency and this spring has been no exception. Though the team showed interest in a few veteran players on the market, Green Bay has yet to bring in anyone new to its roster. Along with the free agents that signed elsewhere, the Packers also lost nose tackle B.J. Raji, who opted to retire. The good news is that Green Bay still has some of their own free agents they can re-sign in an effort to reload their depth chart.
Free agent arrivals: Safety Michael Griffin (Titans), offensive guard Alex Boone (49ers), linebacker Travis Lewis (Lions), offensive tackle Andre Smith (Bengals), linebacker Emmanual Lamur (Bengals).
Free agent departures: Receiver Mike Wallace (Ravens), cornerback Josh Robinson (Buccaneers).
Notable re-signed players: Guard Mike Harris, linebacker Audie Cole, tight end Rhett Ellison.
Summary: Upgrading the offense was an important task for the Vikings this spring, and the team did so by overhauling its offensive line. Boone was one of the top interior linemen on the market and Smith has been a dependable starter, though one coming off a rough year with the Bengals. Minnesota still has work to do, however. Receiver was a need heading into free agency, and has become an even larger one given the departure of Wallace. On defense, the secondary should see improvement with Griffin, who has 25 career interceptions and recorded more than 100 tackles in each of the past two seasons.
