Williams gained 31 yards on 11 carries and six yards on one reception in Thursday's preseason finale against the Rams.
Williams received the start at running back, yet still played into the third quarter, with the extensive playing time suggesting he isn't all that secure in his presumed role as Ty Montgomery's top backup. Fellow rookies DeVante Mays and Aaron Jones were quiet while mostly taking third-team reps throughout the preseason, but they both stepped up Thursday and outplayed Williams. While he'll still likely enter Week 1 as the Packers' No. 2 back on the depth chart, Williams may have more competition for backup work than previously believed.
