The Packers had minus-12 yards and no first downs on nine first-quarter plays. They have four plays, 74 yards and a touchdown in the second.
Green Bay scored in a hurry in the second quarter, needing only 1:35 to get into the end zone.
The touchdown came three plays after Rodgers found Marquez Valdes-Scantling all alone for a 47-yard gain to the Chicago 27.
Rodgers did not look good until his fourth drive, and Mitchell Trubisky still is trying to find his way, starting 5-for-10 for 48 yards.
