Zach Zenner

Few tailbacks simultaneously serve as special-teams ace and highly-efficient offensive depth, but that's exactly what Zenner was down the stretch last season when he produced three touchdowns and 4.8 YPC over 55 attempts. His viability as a fill-in starter also gained steam after Zenner closed the season with a 123-total-yard performance against Green Bay in Week 17. Zenner's problem is that his primary competition for the No. 2 role ahead of this campaign (C.J. Anderson) had an even better finish to 2018 in the form of a two-game stretch that saw Anderson rack up 299 rushing yards on 7.0 YPC to help propel the injury-riddled Rams into postseason play. The pecking order for carries - and even roster spots - behind Kerryon Johnson likely won't be settled until the preseason, and even then it could be a fluid situation.
