The rookie running back impressed at Lambeau Field in his first professional live contact display, according to Bob McGinn of the Milwaukee Journal Sentinel.
"He (Lacy) went in there and proved he could run the ball effective," running back Alex Green said. "Even when he was a little bit winded he still ran hard and finished runs. Picked up the blitzes when he had to. I thought he did great."
Lacy had eight carries for 65 yards, including gashes of 7, 8, 16 and 19 yards.
Lacy's power was on display during the scrimmage, and he looks primed for a lot of short-yardage and goal-line touches in his rookie season. Reports that he is improving in his pass protection (something all rookies struggle with out of the gate) also will help him see the field earlier and more often.
