Jaylen Warren sitting there at running back 13... I am the lowest of anyone on the site on Jaylen Warren... Jaylen Warren has been wildly efficient in fantasy football this season, but the usage has really trended back... 14 for 50, 18 for 101, 17 for 103, averaging 5.6, and 8.4 yards per carry... I still like Jaylen Warren... same tier.
STACKED’s take
RB13, lowest on site; efficient but usage trending down to median
Ranked RB13 for Week 10, the lowest ranking on the site for Warren. Source acknowledges this could be too low but finds it very hard to rank Warren ahead of Jonathan Taylor, Derrick Henry, or Chase Brown based on projected performance. Warren has been wildly efficient in fantasy this season but usage has trended back toward his median; recent touch splits show 14 for 50 yards, 18 for 101 yards, and 17 for 103 yards, averaging 5.6 and 8.4 yards per carry. Source still likes Warren and has placed him in the same tier as Chase Brown, noting the Steelers-Bengals matchup is not the greatest but not terrible, and expects the game to go over the total. Source would struggle to choose between Warren and Brown if forced to decide.
