Dao versus Warren for the Pittsburgh Steelers. might be, frankly, this might be the biggest question of the fantasy football season because if either of these guys dominates the other, both in terms of targets and in the highv value touches, they could easily be the top 15 running back... both Jaylen Warren and Kenneth Gainwell were averaging over four targets per game in this backfield last year... a true time share probably favors Jaylen Warren for the Steelers.

STACKED’s take

Positive signalProjection

Top-10 upside if he dominates Dao in targets and high-value touches.

Mattek Fantasy Football identifies the Rico Dao versus Jaylen Warren backfield split as potentially the biggest question of the fantasy football season. If Warren dominates in both targets and high-value touches, he could easily finish as a top-10 running back. Warren and Kenneth Gainwell both averaged over four targets per game in the Pittsburgh backfield last year; if the Dao-Warren split mirrors the Gainwell-Warren split, it will be roughly even, but a true time share probably favors Warren for the Steelers. There are many fantasy points available in the Pittsburgh Steelers backfield.
