Sit or Start recommendations for EVERY fantasy-relevant player in Week 18 of the 2025 NFL season!

Game Info

 

Kickoff: Sunday, January 4, 2026, 4:25 p.m. ET

Location: SoFi Stadium, Inglewood, CA

Network: FOX

 

Arizona Cardinals

 

Quarterback

Jacoby Brissett: START, QB1

Jacoby Brissett and the Arizona Cardinals haven’t been playing for anything other than next year for quite a while. Brissett is expected to play a full game against the Rams and could see L.A.’s second-stringers in the second half of the game. He’s been one of the most consistent options this season and an easy start in Week 18.

 

Running Back

Michael Carter: START, RB2
Emari Demercado: SIT

Michael Carter was one of the biggest disappointments of fantasy championship weekend, failing to score even seven points against the Bengals and their status as the top matchup for running backs. But there’s few Week 18 options who have as safe of an expected workload as Carter, and if the Rams sit their starters early, he could face little resistance in the second half of the game.

 

Wide Receiver

Marvin Harrison Jr.
Xavier Weaver
Michael Wilson: START, WR1

MICHAEL WILSON WR1 SZN

 

Tight End

Trey McBride: START, TE1

THE TE1 this season and likely a pick in the top three rounds in 2026. The easiest auto-start this season. 

 

Defense/Special Teams

Arizona Cardinals: SIT

Not even against the Rams’ backups. 

 

Los Angeles Rams

 

Quarterback

Matthew Stafford: SIT, QB2 (startable in Superflex)

The hesitation to start Matthew Stafford in 1QB leagues is obviously not due to his talent, just how much he’ll see the field. At the time of writing, it was expected for the Rams’ starters to play. But Los Angeles is locked into either the fifth or sixth seed, so there’s a high probability the starters are pulled early. The Rams are an explosive enough offense to put up plenty of points prior to the second half of the game, but it’s a situation I’d prefer to avoid. 

 

Running Back

Kyren Williams: SIT
Blake Corum: SIT
Ronnie Rivers: SIT

Both Kyren Williams and Blake Corum are dealing with ankle issues, with Williams practicing in a limited fashion and Corum not at all at the time of writing. Even if one or both are active, I foresee just a few drives for each, but not enough to make them fantasy viable for Week 18. 

 

Wide Receiver

Davante Adams
Puka Nacua: START, WR2
Xavier Smith: SIT

Expect Davante Adams to be inactive once again as he tries to get healthy enough to play in the postseason. As of now it looks like Puka Nacua will suit up in some form or fashion, but as I mentioned in Stafford’s blurb, expect the starters to be pulled early. Puka can put up WR2 numbers in a half, but any Ram is a risk this week. 

 

Tight End

Colby Parkinson: SIT

Colby Parkinson likes to score double-digit fantasy points every week when he’s on people’s benches, just not when we all tout him as a top-five option. He could be a fine option if he plays the majority of the game, but we don’t know what to expect.

 

Defense/Special Teams

Los Angeles Rams: START

The Rams are top 10 in sacks and top five in turnovers forced, but could succumb to some second-half garbage time if they sit their starters early. But they’re still a viable D/ST start.
