EDEN PRAIRIE, Minn. — As General Manager Rick Spielman predicted the previous week, the Vikings were **patient** when the free agency market opened Tuesday.

The offseason activity featured a***bigger splash** *Friday evening when Minnesota traded undisclosed compensation to Miami to acquire Dolphins receiver Mike Wallace.

Wallace arrived at Winter Park Saturday to meet Head Coach Mike Zimmer for the first time and told Vikings.com he wants to be known as a **hard worker**. The deep threat that Wallace has provided in his first six pro seasons prompted a question about Randy Moss during a conference call with reporters. Wallace communicated a sincere respect for Moss (**click here** for a comparison).  

Prior to the Wallace trade, Minnesota completed a trade of quarterback Matt Cassel for a draft pick that the team didn't announce, and signed veteran Shaun Hill to back up Teddy Bridgewater. The acquisition will bring Hill back to the locale where his pro career began (2002-05) and reunite him with Vikings Offensive Coordinator Norv Turner, who coached Hill in San Francisco in 2006.

Hill and Bridgewater have already begun communication and plan to set up challenges at practice to stoke competitive fires. **Click here** to read more about Hill's plan to support Bridgewater.

Additionally, the Vikings have reached deals to bring back:

DT Tom Johnson (career-high 6.5 sacks in 2014 | **Read More**)

RB Matt Asiata (tied for third in NFL with nine rushing TDs in 2014 | **Read More**)

OL Joe Berger (nine starts in 2014 | **Read More**)

LS Cullen Loeffler (snapped on 10 of 11 longest field goals in team history | **Read More**)

Departing free agents Jerome Felton signed with Buffalo, and Jasper Brinkley signed with Dallas this week. Christian Ponder signed with Oakland Friday, the Raiders announced. Greg Jennings was released Saturday.

Here's a brief look at other activity in the NFC North:

Green Bay

Two re-signings were top priority for the Packers offense. Receiver Randall Cobb, a top target for Aaron Rodgers, and tackle Bryan Bulaga, one of the QB's top protectors, reached deals to return to Green Bay. The Packers also reached a deal to bring back Scott Tolzien to back up Rodgers.

The defense, however, has had a couple of departures so far: A.J. Hawk signed with Cincinnati, and CB Davon House joined Jacksonville.

B.J. Raji and Tramon Williams highlight 2014 Packers defenders still on the market.

Detroit

The departures of starting defensive tackles and former first-round picks Ndamukong Suh (to Miami) and Nick Fairley (to St. Louis) have generated the most buzz in Detroit. Fullback Jed Collins also has left, agreeing to a deal with Dallas.

The Lions have locked down kicker Matt Prater, who ended a streak of perplexing kicking woes of others in 2014, and signed defensive tackle Tyrunn Walker to plug part of the gaps left by Suh and Fairley leaving.

Reggie Bush, who was cut by Detroit and joining San Francisco, is the biggest change to the offense, followed by the possible replacements of 14-year veteran center Dominic Raiola and nine-year pro guard Rob Sims.

Chicago

A team in transition with a new coach (John Fox), GM (Ryan Pace) and base defensive front (3-4 instead of 4-3), the Bears set the wheels of change in motion by acquiring linebacker Pernell McPhee. Chicago also has signed safety Antrel Rolle to help its secondary and added receiver Eddie Royal after trading Brandon Marshall to the New York Jets.

The Bears cleared any speculation about Jay Cutler's status as starting QB, and reached an agreement to bring back reserve Jimmy Clausen.

Safety Chris Conte has departed for Tampa Bay, and defensive tackle Stephen Paea has signed with Washington.

Cornerback Charles Tillman and linebacker Lance Briggs, who each have 12 seasons under their belt, are the biggest names on the Bears that have hit the market.
