Most rushing offenses would suffer greatly if the top three running backs on the depth chart were all out with injury, but the San Diego Chargers haven't, thanks to an undrafted rookie from Buffalo.

Oliver became the first rookie in the NFL this season to have multiple games with 100 or more rushing yards—in fact, he's the only rookie in the NFL this season to have multiple games with 100 or more yards from scrimmage—when he rushed for 101 yards on 26 carries and gained 23 more yards on four receptions against the Oakland Raiders on Sunday.

After rushing for 114 yards and gaining 68 yards in Week 5 against the New York Jets, Oliver now ranks second among all rookies in yards from scrimmage, despite the fact he received just 16 total touches in San Diego's first four games.

While Oliver shot to the top of this week's running back rankings, Terrance West's move down the board from first to fourth corresponds with how he has dropped down the Cleveland Browns' running back depth chart since Ben Tate's return from injury. Despite a hot start, West was kept off the team's 46-man game-day roster on Sunday against the Pittsburgh Steelers, as the Browns decided to roll with Tate, Isaiah Crowell and Glenn Winston as their three backs.

Crowell, a fellow rookie, continued to get playing time as the change-of-pace back spelling Tate. He took advantage of his opportunities, rushing for 77 yards on just 11 carries, but also fumbled the ball twice, one of which was recovered by the Steelers.

Jeremy Hill hasn't had any huge games for the Cincinnati Bengals, but he's been the most consistent performer of the rookie RBs as the team's No. 2 back behind Giovani Bernard. Jerick McKinnon had 82 combined yards as the Minnesota Vikings lead back Sunday in his first game starting ahead of Matt Asiata, but his struggles in pass protection showed why the Vikings might have been skeptical to move him to the top of their depth chart in the first place.
