2025 rehearsal

From the backtest — a completed season, run to shake the engine out

This is not the real league. It is the rehearsal run against a season whose results were already known, and it happened before the briefing existed — so Grok 4.5 was drafting from raw projections with no view of replacement level.

Pay modestly to lock slot 1 for Chase’s 328.3 projection while keeping most of the $100 for 14 weeks of FAAB and the playoff auction.

Projected is the season projection this league computed under its own scoring rules. Actual is what the player really scored across all 18 weeks. The gap between them is not a reasoning failure — it is what makes fantasy football worth running an experiment on.

Every pick, and why

Josh AllenR1 · #2 · QB · conf 0.85full record
Take the highest-projected player available in Josh Allen to maximize season-long scoring at the scarce QB slot.
Closest call: Ja'Marr Chase (7564) for his adp 1 and 328.3 projection as a foundational WR, but his lower proj_season_points versus Allen made the QB the better raw points choice.
De'Von AchaneR2 · #15 · RB · conf 0.85full record
Taking De'Von Achane at 15 for elite RB value with QB already locked.
Closest call: Puka Nacua (proj_season_points 276.8, adp 21) for the higher raw projection at WR, but Achane's ADP 2 scarcity at RB outweighed it.
Nico CollinsR3 · #18 · WR · conf 0.72full record
Take Nico Collins, the highest-projected available player, to fill a starting WR hole after securing QB and RB1.
Closest call: Brock Bowers (11604) — elite TE proj_season_points 250.8 and adp 9 falling to 18, but 24+ fewer projected points than Collins and WR need is more urgent at 0/2.
Ladd McConkeyR4 · #31 · WR · conf 0.75full record
Take the highest-projected available skill player Ladd McConkey to fill WR need.
Closest call: Omarion Hampton (12507) with proj_season_points 235.9 and RB need, but McConkey's 4.3 higher projection and better adp edged him out.
Alvin KamaraR5 · #34 · RB · conf 0.85full record
Take Alvin Kamara to fill the critical second RB slot with elite projected production and massive ADP value.
Closest call: George Kittle (4217) with proj_season_points 208 and adp 23 for TE scarcity, but RB starter need outranks TE with only one RB currently rostered.
Marvin HarrisonR6 · #47 · WR · conf 0.72full record
Take Marvin Harrison as highest-projected available skill player to lock in elite FLEX/WR3 production.
Closest call: Mike Evans (2216) — nearly identical projection and far lower ADP 31, but 230.1 still sits below Harrison’s 234.8 so pure points win.
Jaxon Smith-NjigbaR7 · #50 · WR · conf 0.82full record
Take fallen WR Jaxon Smith-Njigba at elite projected value to lock FLEX and WR depth.
Closest call: Breece Hall (player_id 8155, proj_season_points 213.8, adp 55) for RB depth, but lower projection and less ADP discount than JSN.
Jaylen WaddleR8 · #63 · WR · conf 0.78full record
Take Jaylen Waddle at clear ADP/projection value to lock in a high-upside FLEX while TE can wait one pick.
Closest call: Mark Andrews (5012) — adp 63 and fills TE 0/1 immediately, but proj_season_points 165.5 is far below Waddle and Engram remains as TE insurance.
QB already filled by Josh Allen so Purdy/Nix (proj ~311) are unnecessary now — value(s) not in DATA: 311
Evan EngramR9 · #66 · TE · conf 0.82full record
Secure the last high-upside TE to fill the empty starting TE slot before the position dries up.
Closest call: Rashee Rice (proj_season_points 201.3) for WR depth/upside, but TE is the only unfilled starter skill position and Rice would sit on bench.
Emeka EgbukaR10 · #79 · WR · conf 0.75full record
Taking Emeka Egbuka as the highest-projected FLEX option to lock in starter-level production.
Closest call: Jakobi Meyers (player_id 5947, proj_season_points 193.16) was essentially identical in projection but Egbuka edges him by 0.04 and I preferred the slightly higher number.
Kenneth WalkerR11 · #82 · RB · conf 0.78full record
Take Kenneth Walker for critical RB depth and strong season-long projection while K/DEF can wait.
Closest call: Jakobi Meyers (5947, proj_season_points 193.16, adp 54) — higher raw points but surplus WR depth makes the RB scarcity more urgent.
Jordan AddisonR12 · #95 · WR · conf 0.75full record
Taking Jordan Addison for high-upside WR depth and FLEX points with the best non-QB projection left.
Closest call: David Njoku (4033) with adp 30 and proj_season_points 159.5 offered elite TE value and FLEX eligibility, but lower projection than Addison and I already roster Evan Engram at TE.
Daniel CarlsonR13 · #98 · K · conf 0.85full record
pool narrowedTake the highest-projected kicker available while the pool is locked to K/DEF needs.
Closest call: Chase McLaughlin (6650), nearly identical proj_season_points 154.28 but Carlson edges him at 154.87.
Los Angeles ChargersR14 · #111 · DEF · conf 0.90full record
pool narrowedTake the Chargers DEF to fill the mandatory empty DEF slot with the higher season projection.
Closest call: KC DEF, nearly identical projection but 0.92 fewer proj_season_points than LAC.
Dak PrescottR15 · #114 · QB · conf 0.85full record
Taking Dak Prescott as QB insurance and highest-upside bench piece with the final pick.
Closest call: C.J. Stroud (9758) — nearly identical 286 proj_season_points but worse adp 135 and no other edge in the DATA.
