De’Von Achane is not a one-hit-wonder: Achane racked up over 100 rushing yards and averaged over 10 yards per carry for a second straight game.

More rookies get more playing time: Achane wasn’t the only rookie to get more playing time relative to other players on the roster in Week 4.

Some backfields become clearer, others more complicated: There were multiple situations where a backfield committee favored the starting running back more heavily. Others that had a clear starter moved closer toward a committee.

PFF's fantasy football recap focuses on player usage and stats, breaking down all the vital information you need to achieve fantasy success in 2023. Here, we touch on only players who are relevant in fantasy football leagues.

These are my 10 biggest reactions to the games from the Sunday slate. To get a more in-depth breakdown, check out my full Sunday recap.

WR:CB Matchup Chart

De’Von Achane starts taking over the Dolphins' backfield: The breakout rookie led the Dolphins' backfield in offensive snaps and production.

  • Raheem Mostert had a slight lead in snaps played in the first quarter — 8-6. The two broke even in the second quarter at 10-10. Achane took a slight lead in the third quarter at 12-9, and Achane dominated the fourth quarter at 11-2.
  • Salvon Ahmed was injured and didn’t play last week. He only played in four snaps in the middle of the fourth quarter on third- or fourth-and-17-plus yards to go.
  • Mostert might remain the technical starter going forward as some teams prefer giving their veteran back the first snap of the game, but Achane is the one who is a must-start going forward, while it will be much harder to start Mostert now.
  • Jeff Wilson Jr. is eligible to return from injured reserve this week and could factor into the backfield. Based on how well Achane is playing, it shouldn’t be at his expense. This was also Mostert’s one poor performance this season, so Wilson might be limited to a few snaps per game.

 

Good and bad news for James Cook: The Bills' breakout running back received all the goal-line work but none of the third-down or two-minute drill snaps.

  • Cook led the team in carries with 12 but only gained 29 yards. He also caught a pass for 48 yards.
  • To his fantasy managers ‘ delight, he scored a touchdown on his second goal-line opportunity.
  • The only problem is he’s starting to share more time with the other running backs.
  • Part of this was Damien Harris playing most of the fourth-quarter snaps, but another part was Latavius Murray often taking the passing down work.
  • Murray played every third-and-long snap in the first three quarters. While we sometimes see a change in third-down back when a player is needed for pass protection, Murray either ran a route or ran the ball on each of those plays.
  • Cook should continue to see double-digit carries each game, but his targets have declined in each game, and they might remain low going forward.
