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 Gemini 3.1 Pro was drafting from raw projections with no view of replacement level.

“Bidding $0 preserves the entire $100 budget for the season and the critical playoff free-agent auction, while Slot 4 offers the highest projected start.”
The roster it built
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
Saquon Barkley provides elite RB production and value at the 1.08 draft slot.
Closest call: CeeDee Lamb, who has the exact same projected season points (302.5) but a lower ADP (13).
CeeDee Lamb provides the highest projected scoring output among available skill position players.
Closest call: Justin Jefferson was heavily considered due to his higher ADP (7), but Lamb's superior projection (302.5 vs 297.3) makes him the better mathematical choice.
Jonathan Taylor offers immense value at pick 24, falling well past his ADP of 12.
Closest call: Josh Jacobs, who actually has a slightly higher projection (263.3) but a much lower ADP (25), making Taylor the better value pick.
Drafting Tyreek Hill fills the required WR2 slot with an elite producer whose ADP aligns perfectly with this pick.
Closest call: Josh Jacobs, who has a slightly higher projection of 263.3 points, but would have been relegated to the FLEX spot since both RB slots are already filled by Saquon Barkley and Jonathan Taylor.
Tee Higgins provides elite FLEX value, perfectly matching the current draft slot.
Closest call: James Conner (player_id 4137) was strongly considered due to his ADP of 39, but Higgins offers slightly higher projected season points (234.7 vs 223.5).
James Conner provides excellent value and depth as the highest-ranked player available by ADP.
Closest call: Travis Kelce was considered to fill the starting TE slot, but his ADP of 48 and lower projection than Hockenson made Conner the better value.
Drafting Jerry Jeudy provides immense value as he falls significantly past his ADP.
Closest call: Tony Pollard, who is also a strong value with an ADP of 49 and a projection of 212 points.
Securing a starting quarterback before the position is depleted, as the next team on the clock also needs one.
Closest call: Mark Andrews, who fills the empty TE slot and has an ADP of 63, but securing a QB was prioritized due to Team G's roster needs.
⚑ Team G picks next at 58 and currently has 0 QBs, making a run on the position likely. — value(s) not in DATA: 58
Mark Andrews fills the starting TE slot with the highest projected points available at the position.
Closest call: David Njoku, who has a much higher ADP (30) but a lower season projection (159.5).
Isiah Pacheco adds premium depth to the running back room with the highest projection among available backs.
Closest call: David Njoku, who has a remarkable ADP of 30, but was passed over due to his lower projection (159.5) and the fact that Team H already rostered Mark Andrews.
Ricky Pearsall offers the highest projected season points among available flex options to strengthen the bench.
Closest call: David Njoku, who has a remarkable ADP of 30, but his projected points of 159.5 are significantly lower than Pearsall's 190.9, and the roster already has Mark Andrews at TE.
Drafting Jaylen Warren provides immense value at pick 89, well past his ADP of 52.
Closest call: David Njoku, who has an ADP of 30, but Team H already has Mark Andrews at the single TE slot.
pool narrowedDrafting Harrison Butker to fill the required Kicker slot with the highest projected points available.
Closest call: Tyler Loop (K), who has the exact same proj_season_points (147.69) as Butker.
pool narrowedSelecting the highest-projected defense to fill the mandatory starting slot.
Closest call: Pittsburgh Steelers (PIT), but their projected season points (136.93) are lower than Detroit's (138.01).
Adding Jordan Love provides crucial depth and a high-upside option at quarterback to complete the roster.
Closest call: Cooper Kupp, who has a higher ADP (88) and strong projection (168.5), but securing a second QB is a higher priority for roster balance than adding a 6th WR.
