While many of the top 10 running backs are the starters that fantasy managers drafted in the early rounds, the next group of running backs (the RB2s) are a lot of backups, filling in for injured starters. In Chicago, when David Montgomery went down, it seemed that Damien Williams would be the next man up. Unfortunately for managers that rostered Williams, it is actually Kahlil Herbert who is the running back to start. In the past four games, the rookie has more than 70 rushing yards in each game. He has one touchdown as well and is the Chicago back to start.

Things are a little murkier in both Philadelphia (Boston Scott and Jordan Howard getting goal-line work) and Tennessee. With Derrick Henry out, newcomer Adrian Peterson will get some work. Jeremy McNichols has also been on the team and is the handcuff to Henry. It seems that both will play, but McNichols will be a better PPR option and Peterson is a better bet to find the end zone.
