Buffalo changed the names around Josh Allen without proving it wants to change the way it wins. DJ Moore gives the Bills a credible outside receiver, but James Cook returns to an offense that ran whenever the score and down allowed it. The useful question isn't which Buffalo player has the best highlight reel. It's which job is already built into the offense.
Start with Cook when your roster needs dependable rushing volume. Wait on Moore until you can live with an unsettled target order, then consider Buffalo receiver Khalil Shakir in reception-heavy formats or Dalton Kincaid as a tight end swing. Those choices follow how Buffalo creates touches: Cook gets designed handoffs, Shakir works underneath, and Kincaid still needs more routes.
Ray Davis belongs on benches that can afford to hold Cook's understudy.
Should Cook come before every Buffalo receiver?
Yes. Cook owns the role that requires the least imagination.
FFN recorded Buffalo throwing on 56.2% of its offensive plays in 2025 and finishing with a negative pass rate over expectation. The Bills also ran slightly more often than they threw in the red zone. Cook doesn't need Joe Brady's promotion to head coach or Pete Carmichael Jr.'s arrival as offensive coordinator to produce a new identity. He needs Buffalo to keep giving him the first rushing call when it can play from ahead or finish a drive on the ground.
During Buffalo's closing month, Cook handled 78 carries even though the Bills limited him to two snaps in Week 18. That finale drags down the surface numbers without changing the job he held before it. When Buffalo wanted its lead back, Cook was the lead back.
The August 10 half-PPR rankings place Cook at RB6. We'll own the call: draft him in that tier and hold us to a top-six finish at the position. A workload of at least 15 carries a week is the line that keeps the bet intact. His receiving work can turn a steady week into a big one, but the rushing job pays the bills.
Does Moore immediately become Allen's target leader?
He's the best candidate, but a trade doesn't award him the first read. Moore should be the first Buffalo receiver drafted when your roster can absorb some early uncertainty, especially in full PPR. He shouldn't be treated as though the Bills suddenly became one of the league's most pass-heavy offenses.
FFN recorded Moore drawing 22 targets and 14.8% of Chicago's throws during the closing month of 2025. His old role was fading. That history doesn't determine his Buffalo workload, but it explains why September matters: Moore has to win Allen's attention on third down and in the red zone rather than simply add another route runner to the formation.
Brady and Carmichael have every reason to feature Moore as the outside answer Buffalo lacked. Better receiver talent can improve efficiency, create easier throws for Allen, and pull coverage away from the middle. It still can't create extra pass attempts by itself.
I want Moore first among the Bills' pass catchers because his outside routes give Allen something this offense lacked. I also want to see the third-down and scoring-area targets become his before treating the takeover as complete.
Is Shakir or Kincaid the better PPR wait?
Shakir fits managers who need catches. Kincaid fits managers willing to carry more weekly volatility for a possible edge at tight end.
FFN recorded Shakir collecting 24 targets and a 19.3% share of Buffalo's throws late in 2025. Week 17 against Philadelphia is the snapshot to keep: seven targets while playing 78% of the offensive snaps. He doesn't have to beat Moore on every route to matter in PPR. Quick access throws, option routes, and underneath catches can keep him involved when Moore gets the deeper or boundary work.
Kincaid's route to relevance asks for a more visible change. FFN recorded 16 targets and a 29.4% snap share for him during Buffalo's closing month. In the three appearances before that stretch, he averaged 4.7 targets. The talent case remains, but points can't follow a player who isn't consistently on the field. Moore's arrival also adds another claim on middle-of-the-field and scoring-area throws.
Take Shakir when your bench needs a receiver who can collect catches without leading his team; his underneath routes and rising snap share can support that job. Kincaid becomes attractive after the dependable tight ends are gone, provided your roster can carry an uncertain route load.
Is Davis necessary insurance for Cook?
Davis is useful insurance with limited standalone appeal because Cook owns the lead carries and scoring-area work. Prioritize Davis when Cook is already on your roster or when the rest of your bench has enough immediate utility.
Week 18 against the Jets showed what Buffalo can hand Davis once Cook leaves the plan. Davis took 21 carries, drew two targets, and played 64% of the offensive snaps. Cook played just 3%. That's evidence Davis can handle the work, but it isn't evidence of a weekly committee.
Across the late-season stretch, Davis totaled 25 carries and played 21.6% of the snaps. The contrast is the entire case. He can take over when the door opens. Until then, his value depends on Cook leaving the field.
What would make Cook the wrong first bet?
The risk is a real philosophical shift: Buffalo sustains a pass rate above 60% in competitive game situations and moves enough scoring-area work toward Allen. Pair that change with Moore earning at least one quarter of the throws, and the Bills could support Moore plus a second pass catcher while Cook falls short of the RB6 tier.
FFN's 2025 baseline put Buffalo at a 56.2% pass rate, including 55.2% in neutral situations, with a slight red-zone lean toward rushing. One productive receiver week won't prove that profile changed. A month of more early-down throws would show the coaching staff has reordered the offense.
The first reveal may come before the box scores settle it. Moore's third-down presence and Allen's attention inside the 20 will show where the passing game bends. Buffalo's leading receiver will be decided on those snaps before it looks obvious in a season total.
