Who Should I Start? Brian Robinson Jr. or Kyren Williams

Tuesday, December 30, 9:27 PM

Across 16 games this season, San Francisco 49ers running back Brian Robinson Jr. has recorded 90 carries for 391 yards and two touchdowns. The 26-year-old has spent the entirety of 2025 in a secondary role behind star 49ers running back Christian McCaffrey, who leads the NFL with 399 touches heading into the team's Week 18 matchup against the Seattle Seahawks. Robinson Jr. has been fairly efficient when given the opportunity so far this season, averaging 4.3 yards per carry. He's also proven to be a productive lead back at certain points in his career, recording 2,720 rushing yards and 22 total touchdowns across 57 career NFL games. However, his production upside in San Francisco is firmly capped as long as McCaffrey remains healthy. Robinson Jr. should not be on fantasy radars heading into Week 18.

Los Angeles Rams running back Kyren Williams (ankle) was listed as a limited participant on Wednesday's estimated injury report, according to Adam Grosbard of the Los Angeles Daily News. Williams suffered a minor ankle injury in Monday night's loss to the Atlanta Falcons and was able to return to the game. Meanwhile, fellow RB Blake Corum sprained his ankle in the second quarter and never returned. With Corum out in the second half, Williams saw more work out of the backfield for the Rams as they attempted a comeback. If Corum is unable to play in the Week 18 regular-season finale against the division-rival Arizona Cardinals this Sunday, the 25-year-old Williams could see a bigger workload again, although Ronnie Rivers would also be mixed in. The Rams are fully expected to play their starters in Week 18 to keep them fresh going into the postseason.
