Who Should I Start? Raheem Mostert or Ty Johnson

Saturday, December 13, 1:01 AM

Las Vegas Raiders running back Raheem Mostert has spent most of this season backing up rookie Ashton Jeanty, and he should remain in that role ahead of Week 15 against the Philadelphia Eagles. The 33-year-old battled a knee injury during practice this past week but has been removed from the injury report and will play on Sunday, barring a setback. He has been held to just one touch in each of his last two games, and he ranks as the overall RB75 in PPR leagues this season. On one hand, the Eagles present a favorable matchup for any running back. After all, Philadelphia has allowed the eighth-most fantasy points, fifth-most receiving yards, and second-most receiving touchdowns to opposing running backs in 2025. On the other hand, though, the Purdue product is clearly nothing more than a change-of-pace back behind Jeanty in this Vegas offense. He's averaging just 3.1 touches per game and has played fewer than one-third of the snaps in each of his last eight contests. Mostert ranks as the overall RB72 in this week's RotoBaller fantasy rankings, and he can be left on waivers in all leagues.

Buffalo Bills running back Ty Johnson carried the ball four times for 13 yards and added 15 receiving yards on three catches against the New England Patriots. Johnson entered the 2025 season as the expected RB3, behind James Cook and second-year back Ray Davis. However, Johnson's receiving ability has earned him more snaps than Davis, outsnapping him 29% to 12% on the season. He faces a Cleveland Browns defense that has ranked middle-of-the-pack against running backs this season but has struggled to slow down Tony Pollard and D'Andre Swift in back-to-back weeks. While Johnson carries a safe floor with his strong skill set in the receiving game, his upside is capped by Cook's dominance of touches. Johnson should be out of starting lineups in fantasy leagues this week.
