Green Bay Packers (1-2) at Chicago Bears (2-1)

Sunday, 1 p.m. ET, at Soldier Field, Chicago — TV: CBS

*TV announcers: Kevin Burkhardt, John Lynch, Pam Oliver

*Keys to the game: Green Bay returns to the scene of a 33-28, playoff- and division-clinching Week 17 win last season with plenty of offensive worries. QB Aaron Rodgers has dominated the series. He’ll see a healthy diet of cover-2 shells that strive to take away WR Jordy Nelson. Rookie CB Kyle Fuller is a physical, stout ball magnet and the first-round pick is not skipping a beat filling the shoes of veteran Charles Tillman (triceps).

Two keys for the Packers’ offense: more from the running game and better blocking on the edges. Eddie Lacy was stuffed repeatedly and fumbled again last week at Detroit. The blocking should be better with RT Bryan Bulaga returning to the lineup. This week, head coach Mike McCarthy took some of the onus off the offensive line saying “Eddie has to play better.”

Chicago’s offensive line is nicked up, and C Robert Garza remains out. The worry is edge protection with OLBs Julius Peppers and Clay Matthews presenting a major challenge for QB Jay Cutler and the front wall. Cutler is showing some ease and confidence in his second year in the Marc Trestman offense with a string of 84 consecutive passes without an interception.

*Matchup to watch — Packers RB Eddie Lacy vs. Bears RB Matt Forte: Neither player is off to a special start. Forte is averaging 3.2 yards per carry and the Packers are at the back of the pack in the NFL with a mere 78.7 yards per game on the ground. Getting RT Bryan Bulaga back closer to full health should boost Green Bay’s ground game.

*Player spotlight — Bears WRs Brandon Marshall and Alshon Jeffery: Marshall stood out in the teams’ two games last season with a combined 13 receptions for 181 yards and two touchdowns. Jeffery grabbed eight passes for 140 yards and a touchdown in last season’s two games.

*Fast facts: As a member of the Bears, Cutler is 1-7 against the Packers with nine touchdowns and 17 interceptions. … Rodgers has seven interceptions at Soldier Field, his highest total in any opponents’ stadium.

WHO WILL WIN AND WHY

The Packers intend to pick up the pace but getting a strong effort from Eddie Lacy is essential. If Chicago slows Lacy, it strolls to 3-1.

*Our pick: Bears 25-20
