Start/Sit: Week 8

Start: D'Onta Foreman
Foreman made the most of his limited carries with CMC packing his bags to San Fran. Hubbard got the majority of the touches, but Foreman was still utilized well in the win against Tampa. Now with Hubbard out in Week 8, Foreman will immediately take the bulk of the carries, and could see work in the receiving game. He also faces a great matchup against Atlanta, and is behind a top 15 run blocking units Foreman is a RB2 with big upside in Week 8.
Sit: Najee Harris
At this point, the only thing keeping Najee in lineups is his name. Najee has been ranked a RB2 for multiple weeks now, yet has only touches that once. Harris is a talented back who receives good volume, but the only thing that keeps him relevant is if he stumbles into the end zone. He plays in a stagnant offense, behind a bad line, against a juiced up Eagles defense. Harris is a RB3 who might bump up to RB2 if he scores.
Start: Tony Pollard
Pollard finally edged Zeke out in snaps played, and this week Zeke is out altogether. Pollard is an explosive back who makes the most of his touches. He will be the feature back on the ground and in the air. Chicago's defense has allowed the 6th most points to RBs, paving the way for a big Pollard game.
Sit: James Robinson
The temptation to start Robinson is big, with him seemingly filling in for Breece Hall and Robert Salah stating he will ride the hot hand, but the likelihood Robinson wins the snap share is low. Michael Carter Jr. will likely lead the backfield, with Robinson still learning the playbook. Robinson will eventually take over this backfield, but Week 8 is unlikely that week.
Start: DJ Moore
DJ Moore is usually on the other side of these lists, but last week the Panthers showed that they will have to feed Moore, a lot. PJ Walker clearly will give the rock to Moore on any passing down. Moore also has a good matchup against Atlanta's injured secondary. Moore is a volume WR2 in Week 8.
Sit: Amari Cooper
Amari Cooper has made himself valuable this year against man coverage, but unfortunately the Bengals run heavy zone defenses. His target share is great to look at, but the matchup is now looking great for Cooper. Cooper is typically a solid WR2, but he is more of a WR3 against the Bengals.
Start: Brandon Aiyuk
Aiyuk has seen a high target share since week 3, and should see that increase with Deebo being out. Aiyuk is a big play TD threat, who will receive a lot of work in the 49ers offense this week. CMC and Kittle should see their similar workload, but Aiyuk benefits from the arrival of CMC and the Deebo injury. The rams have been inconsistent defensively, and last time these two teams plays, the 49ers offense did what it wanted. Brandon Aiyuk is a high upside WR2 in Week 8.
Sit: Diontae Johnson
Johnson has seen the volume that everyone expected, but has turned that into little nothings. Kenny Picket seems to favor George Pickens and Pat Freiermuth, meaning that Johnson tends to receive the short work underneath. Johnson is a talented receiver, but is playing a dump-off role in a bad offense. Johnson is a WR3 who borders WR4 range at this point.
