Packers haven't filled biggest needs: running back, (another) cornerback

GREEN BAY, Wis. -- When the 2016 season ended with the NFC Championship Game loss at Atlanta, the biggest holes on Green Bay's roster were at running back and cornerback.

Six-and-a-half weeks later -- and a week into free agency -- those voids remain.

In fact, the situation at running back is even murkier now that Eddie Lacy is gone. He signed a one-year, $5.5 million deal with the Seattle Seahawks on Wednesday, becoming the sixth Packers free agent to walk out the door. A seventh, tight end Jared Cook, is a foregone conclusion to join another team.

Lacy joined T.J. Lang (Detroit), Micah Hyde (Buffalo), Datone Jones (Minnesota), Julius Peppers (Carolina) and JC Tretter (Cleveland) in departing Green Bay. They've all left Lambeau Field in the last week, never to return as members of the Packers.

Well, never say never because on Tuesday, the Packers brought back Davon House, the cornerback who two years ago did the same thing as those others and left in free agency. They re-signed him to a one-year deal. But it would be a big ask for House alone to turn around a pass defense that ranked second-to-last in the NFL in 2016.

Running back is perhaps in more dire shape than cornerback, although the way the Packers defended (or didn't defend) the pass last season, that's debatable. The only halfback currently under contract for this season is converted receiver Ty Montgomery. While the Packers like Montgomery's promise as a ball carrier, coach Mike McCarthy was admittedly intrigued by the idea of a Lacy-Montgomery one-two punch.

The Packers now might be forced to bring in one of the veteran running backs given the hole Lacy's departure has created. Adrian Peterson, Latavius Murray, LeGarrette Blount and Jamaal Charles all remain on the market.

The numbers at cornerback look a little better with LaDarius Gunter, Damarious Randall, Quinten Rollins all returning. Demetri Goodson, the most veteran member of the returning group, may not be ready for the start of the season after his late season ACL and MCL tear. The Packers know little about Makinton Dorleant, Josh Hawkins and Herb Waters -- all undrafted free agents who spent time last season on the roster as rookies.

Yes, the Packers have retained or signed just as many players as they've seen leave. But those players -- tight ends Martellus Bennett and Lance Kendricks, outside linebackers Nick Perry and Jayrone Elliott, offensive lineman Don Barclay and House -- haven't filled the two biggest holes on the roster.
