At one point over the summer, Green Bay Packers rookie running back Jamaal Williams appeared to have unseat his colleague Ty Montgomery for the starting gig in the backfield.

Montgomery may have entered the regular season as the starter, however, Williams hung around -- only to drop further down the depth chart a month into the season.

It took a rib injury for Montgomery on Sept. 28 against the Chicago Bears, and not long later (about four carries later), Williams suffered a knee injury that didn't cause him to miss a game. These blessings in disguise are what led to the emergence of another rookie running back -- Aaron Jones.

He'd go on to have two 100-yard games over the next four weeks, making his own case for a lead role in the Packers' backfield. By November, he was the lead running back.

Against the Bears on Sunday, both Montgomery (ribs) and Jones (MCL sprain) were knocked out of the game. Similar to how Jones got his shot, Williams took full advantage of his opportunity and carried the ball 20 times for 67 yards en route to a victory.

"I felt like I came in, sad for Aaron [Jones] and Ty [Montgomery] to go down, but they prepared us enough for next-man is up, ready to go," Williams said after the eighth consecutive win at Soldier Field for the Packers. "I was just ready to go make sure I can go in there and help the team win."

While his stat line may look uninspiringly average, Williams did much more than what could possibly show up on paper. According to Pro Football Focus, Williams earned 55 of his yards after contact and broke seven tackles.

"I love running hard, I love running down-hill. I want to show other things I can do, finesse and jukes and stuff like that. But, it was a little rainy out there, you can't really get your knees up.

"But, the time will come and I'm just taking every opportunity as I can to make sure I'm doing whatever I can to make sure the team wins."

Williams entered Chicago with just 11 carries on the season -- a sample size of eight games. He nearly doubled that against the Bears, showing with almost each carry that he was able to pick up tough yardage and lower his shoulders into contact -- a nice change from Jones' elusive running style.

The depth chart may have undergone a little renovation since September, however, one narrative remains the same: The Packers have an impressive stable of running backs, and that was once again on full display. This is also without another rookie running back in Devante Mays, who has been inactive in all but three games this season.

"As long as we put our mind to it, nobody can stop us," Williams said. "As long as we execute to the way that we practice -- and we know that we can -- we can always score. It's always us just making sure we're all together, being one and being productive at the same time."

Williams may be a big part of the game plan moving forward, but that also may depend on the injuries to the two running backs that were initially ahead of him. Even so, Montgomery's re-aggravated rib injury and Jones' carting off the field in Chicago will likely be a sign that Williams gets starting reps. It may even pave the way for Mays to get his first carries of his career in the coming weeks.
