Packers linebacker Clay Matthews, who had six sacks in his first two games, was was involved in a lot of plays but never took quarterback Jay Cutler to the ground, thanks largely to a solid performance by backup tackle Kevin Shaffer.
"He hung in there against a great player," Smith said. "Our whole line did that."
It was far from a perfect performance by the offensive line. Overall, however, the Bears were satisfied with a line that gave up six quarterback hits and three sacks.
With starting left tackle Chris Williams on the sideline with a hamstring injury, rookie seventh-round draft pick J'Marcus Webb saw the first action of his career while spelling Shaffer.
"This is big," Shaffer said. "We have that attitude that we want to win every week. We're 3-0 and we feel pretty good about where we are right now."
