"You just wait for your opportunities," Williams said. "You really just have to wait for them, keep your head up, keep your momentum up and be about the team. Coaches see that, if you're about the team and you don't care about your stats and stuff like that and how many times you get on the field on offense."

Williams' 3.4 yards per carry didn't tell the whole story of his day. He converted four first downs in the final 16 minutes of the game and was credited by the coaches with seven broken tackles, according to offensive coordinator Edgar Bennett.

A good chunk of his 67 yards came after contact and only twice on his 20 attempts did get stopped for lost yardage or no gain.

It wasn't ideal for the Packers to lose their top two running backs and have to play the second half with only Williams, fullback Aaron Ripkowski and receiver Randall Cobb as backfield options.

At the same, a switch to Williams didn't cause the coaches to alter the game plan.

"We knew going into it based on again his practice habits, starting going all the way back to training camp when he had quite a few opportunities, and then going into the season, he's one of those guys who just keeps working," Bennett said. "He applies what he's doing on the practice field and he had an opportunity (Sunday) to make the most of his opportunities and he did that."

Williams, the first of the three running backs the Packers drafted last offseason, could've easily been rattled by a reduced role in the offense, but instead he embraced the third-string job.

While waiting for work on offense, the 6-foot, 213-pound running back carved out a niche on special teams. For as much publicity as his performance on the ground generated Sunday, he actually earned a game ball for his work on special teams.
