Jaylen Warren

Since Week 12, Jaylen Warren has split the backfield work with Kenneth Gainwell, averaging 13.7 touches and 58 total yards. During those three games, Warren has had a 50.9% snap share, a 33% route share, and a 6.7% target share while seeing six red zone rushing attempts to Gainwell's seven. Overall, among 57 qualifying backs, Warren ranks fifth in missed tackle rate and 15th in yards after contact per attempt. Warren remains an RB2/3 this week with a tough matchup. Since Week 10, Miami has allowed the ninth-fewest rushing yards per game, the 14th-lowest rushing success rate, the third-lowest yards before contact per attempt, and had the sixth-highest stuff rate.

Jaylen Warren and Kenneth Gainwell split the backfield near 50/50 in snaps and touches. Neither was effective as a rusher, but both produced as receivers out of the backfield. They also both scored (Gainwell from inside the RZ, whereas Warren scored on a big pass play).
And admittedly, the playoff matchups aren't good (bottom-of-the-barrel for RBs), so anticipate this production to fall off for the Steelers RBs.
Weeks 16-17 are the worst matchups for RBs. If this stays a committee between Warren and Gainwell, it could be brutal for all parties.
