Who Should I Start? Jaylen Warren or Jahmyr Gibbs

Monday, December 15, 7:43 PM

Pittsburgh Steelers running back Jaylen Warren (illness), who was a late addition to the Week 15 injury report due to an illness, is officially active for the Monday night game against the visiting Miami Dolphins, according to Teresa Varley of Steelers.com. Fantasy managers can leave the 27-year-old in their starting lineups, but Warren may be spelled a bit more by backfield mate Kenneth Gainwell against Miami. Warren has been Pittsburgh's primary RB all year and is averaging 12.0 half-PPR fantasy points per game on 652 rushing yards and four touchdowns on 159 rushing attempts. He's added 30 receptions for 277 yards and another two scores as a receiver. Warren has a pretty high ceiling as an RB2, as he's had double-digit touches in all 12 of his games in 2025 while averaging 15.8 touches and 77.4 scrimmage yards.

Detroit Lions running back Jahmyr Gibbs posted an underwhelming performance in his team's Week 15 loss to the Los Angeles Rams, recording 58 scrimmage yards and zero touchdowns on 17 touches. The 23-year-old's 3.4 yards per touch against Los Angeles was his third-worst mark of the season and his worst since Week 9 against the Minnesota Vikings. On the bright side, Gibbs continues to be a featured player in the Lions' passing game. He saw seven targets in Week 15 and has earned 38 targets across five games since Detroit tight end Sam LaPorta (back) was placed on Injured Reserve with a back injury. Gibbs also out-snapped fellow Lions running back David Montgomery 52 to 18 in Week 15, marking the fifth straight game where Gibbs has logged at least 20 more snaps than his backfield running mate. Despite the frustrating showing against the Rams, Gibbs remains a must-start fantasy running back in Week 16 against the Pittsburgh Steelers.
