Lacy, who was selected in the second round of this year's Draft, has recorded 596 rushing yards and scoring four touchdowns in seven games for the NFC North side so far this season.
The 23-year-old told reporters: "[Our offense] changes a little bit, but guys are just going to have to step up. Everybody knows what they're doing out there, and they're just going to have to go out and play.
"Being able to add another dimension is great. It keeps the defense guessing. They can't just sit out there and play the pass.
"Now they have to respect the run. I think the running back corps has done a great job of adding another dimension to this offense."
The Packers face the Philadelphia Eagles tomorrow.
