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 Claude Opus 5 was drafting from raw projections with no view of replacement level.

Every pick, and why
Ja'Marr ChaseR1 · #4 · WR · conf 0.78full record
Ja'Marr Chase is the consensus best asset on the board and the best fit for full-PPR scoring, so he goes at 4 overall.
Closest call: Jalen Hurts (6904), whose proj_season_points=351.5 is the highest on the board; I passed because the 23.2-point season gap is small relative to the positional gap a full-PPR WR1 (adp=1) creates over replacement, and because Burrow (331.24) gives me a second shot at an elite QB at pick 13.
⚑ RULEBOOK scoring: Reception = 1.0 (FULL PPR) plus 0.1/receiving yard, which maximizes the value of a high-volume target-hog WR; Chase's proj_season_points=328.3 is the top non-QB projection available. — value(s) not in DATA: 0.1
⚑ Hurts' 351.5 edge over Chase's 328.3 is only 23.2 projected season points (~1.7/week), and the QB slot is 1 of 9 starters while WR+FLEX means I start 2-3 receivers (roster_needs: WR 0/2, FLEX 0/1). — value(s) not in DATA: 23.2, 1.7
Christian McCaffreyR2 · #13 · RB · conf 0.72full record
Christian McCaffrey at pick 13 is a four-round value fall (ADP 3) and fills my biggest hole with a full-PPR RB projected for 274 points.
Closest call: Malik Nabers (11632, proj 279.3) was the highest projection available, but taking him would leave me with two WRs and zero RBs against a board where only one RB (Henry, adp 28) remains, and WR depth is deeper later per the available list.
⚑ SCORING is FULL PPR (Reception 1.0), which maximizes value for a pass-catching back; McCaffrey's 274 projection is within 5.3 points of the top available player (Malik Nabers 279.3) while filling a scarcer slot — value(s) not in DATA: 5.3
Trey McBrideR3 · #20 · TE · conf 0.68full record
Trey McBride at 20 locks the last elite tight end and the biggest positional edge left on the board.
Closest call: Amon-Ra St. Brown (274.2) / Drake London (274.4) — higher raw projections, but with two comparable WRs available and only one elite TE, taking a WR now risks conceding the full 39.4-point TE gap while the WR I'd lose is replaceable at 29.
⚑ McBride proj_season_points 247.4 vs the next-best available TE George Kittle at 208 — a 39.4-point gap at a position where only Brock Bowers (pick 19, Team C) is off the board — value(s) not in DATA: 39.4
⚑ roster_counts_by_team shows every team except Team C has TE 0, and eight picks separate me from my next selection at 29 (your_remaining_picks starts at 29), so an adp-17 tight end will not survive — value(s) not in DATA: -17
⚑ QB is not urgent value: Mahomes 327.02 is only 13.2 points above Kyler Murray 313.86, and five QBs are already drafted (Lamar 1, Allen 2, Daniels 3, Hurts 5, Burrow 11), leaving only Teams G and H as QB-needy bidders — value(s) not in DATA: 13.2
Bucky IrvingR4 · #29 · RB · conf 0.78full record
Bucky Irving at 29 is the best value on the board — an ADP 8 running back with the highest projection of any non-QB available, and he fills my open RB2 next to McCaffrey.
Closest call: Ladd McConkey (proj 240.2, adp 29) — exactly on-value at my slot and I need a WR2, but he is a fair-price pick rather than a discount, and Garrett Wilson at the same 240.2 projection with adp 47 gives me a comparable WR at pick 36 or 45, so WR is the position I can defer.
Patrick MahomesR5 · #36 · QB · conf 0.76full record
Take Patrick Mahomes at 36 — the highest projected player left by nearly 100 points and the last elite QB before Teams G and H, who both still need one, pick eight times before my next selection.
Closest call: Terry McLaurin (5927, adp 34, 234.7) — a WR2 next to Chase would have been the positionally cleaner fit, but taking him risks both QBs (327.02 and 313.86) vanishing across picks 37-44 to the two QB-less teams, leaving me with a huge hole at a mandatory starting slot.
⚑ Mahomes proj_season_points 327.02 is the top mark in `available`, 92.2 points clear of the best WR left (Marvin Harrison 234.8 / Terry McLaurin 234.7) for a slot I must fill (roster_needs QB 0/1). — value(s) not in DATA: 92.2
⚑ draft_board shows 5 QBs already gone (Lamar Jackson pick 1, Josh Allen 2, Jayden Daniels 3, Jalen Hurts 5, Joe Burrow 11), and roster_counts_by_team lists only Team G {RB:2,WR:2} and Team H {RB:2,WR:2} with no QB besides me — the exact two teams holding picks 39, 40, 41, 42 before my_remaining_picks resumes at 45. — value(s) not in DATA: 40, 41, 42
⚑ Only two QBs remain in `available` (Mahomes 327.02, Kyler Murray 313.86); if both go in picks 37-44 there is no comparable option, whereas WR depth persists with two ~235-point WRs plus Kittle (208) and LaPorta (182.4). — value(s) not in DATA: 37, -44, 235
⚑ Rulebook scoring rewards volume QBs (Passing TD 4, passing yards 0.04, rushing TD 6) and I still have 10 picks (45-116) to fill WR2, FLEX, K (Aubrey 183.65 / Bates 159.28) and DEF (DEN 150 / PHI 149.94), positions still stocked in the pool. — value(s) not in DATA: 0.04, -116
Tetairoa McMillanR6 · #45 · WR · conf 0.74full record
Take Tetairoa McMillan at 45 to fill WR2 with the highest-demand receiver on the board, betting Marvin Harrison's ADP 83 lets him survive to my pick at 52.
Closest call: Marvin Harrison, who actually projects higher (234.8 vs 231.2); I passed only because his adp 83 versus McMillan's adp 36 says he is the one who survives seven more picks, so I take the scarcer asset first and target Harrison at 52.
⚑ roster_counts_by_team shows Team G (WR 3) and Team H (WR 3) hoarding receivers and Team A/Team B at WR 2 with picks in front of me at 46-51, so WR demand ahead of my next pick is real — value(s) not in DATA: 46, -51
Courtland SuttonR7 · #52 · WR · conf 0.68full record
Courtland Sutton fills my open FLEX with the highest-valued skill player left on the board (ADP 50, proj 219.8) and gives WR depth behind Chase and McMillan.
Closest call: Jameson Williams (8148, proj 222.0) actually projects 2.2 points higher, but his adp of 81 versus Sutton's 50 signals a much wider market disagreement on his role, and for a slot I plan to start every week I take the more consensus-supported target; Tony Pollard (5967) was the third consideration but I already have RB 2/2 with McCaffrey and Bucky Irving.
⚑ Sutton (available: adp 50, proj_season_points 219.8) is the best ADP among all non-QB options; only Tony Pollard (adp 49, proj 212.0) is comparable and he projects 7.8 points lower — value(s) not in DATA: 7.8
⚑ Full PPR scoring (Reception 1.0) favors a high-volume WR in the FLEX slot; Sutton's 219.8 projection is within 2.2 points of the pool leader at WR, Jameson Williams (222.0), while carrying a 31-spot better ADP (50 vs 81) — value(s) not in DATA: 2.2
⚑ Kicker and DEF can wait: roster_needs K 0/1 and DEF 0/1 remain, but I hold 8 more picks (61, 68, 77, 84, 93, 100, 109, 116) and the gap from Brandon Aubrey (183.65) to Jake Bates (159.28) and DEN (150.0) to PHI (149.94) is small relative to a 220-point starting WR — value(s) not in DATA: 220
Calvin RidleyR8 · #61 · WR · conf 0.68full record
With QB/RB/WR/TE/FLEX all filled, I take the highest-projected skill player left in Calvin Ridley (213.4) to upgrade my weekly WR/FLEX floor and ceiling.
Closest call: Brandon Aubrey (proj 183.65) — his projection is only ~30 points below Ridley's and he'd fill an empty K slot that otherwise scores 0, but the drop-off to Jake Bates (159.28) is just 24.4 points and I have seven picks left, so I can address kicker at 68 or 77 while WRs of Ridley's projection will not last.
⚑ Ridley is a boom-week WR profile, and the RULEBOOK notes higher-variance starters are what give a real chance in weeks I'm an underdog, while my locked core (Chase, McCaffrey, McBride, Mahomes) supplies the floor. — cites no DATA field, value, or name
RJ HarveyR9 · #68 · RB · conf 0.68full record
RJ Harvey is the highest-projected player left and fills my thinnest real need — a third startable RB behind McCaffrey and Irving.
Closest call: Rashee Rice (10229, proj 201.3) — essentially identical projection and probably the higher ceiling, but adp is null (unknown, treat as unknown per DATA RULE) which I cannot verify as availability-safe, and he would be my fifth WR behind Chase/McMillan/Sutton/Ridley where marginal points mostly sit on my bench scoring nothing.
⚑ available: Isiah Pacheco proj 191.8 is the only other RB left, 10.2 points lower than Harvey over the season, and adp 77 vs Harvey adp 96 suggests Pacheco is likelier to survive to my pick at 77 — value(s) not in DATA: 10.2
Zay FlowersR10 · #77 · WR · conf 0.72full record
Take Zay Flowers, the highest-projected player left on the board, to upgrade a FLEX spot currently filled by Courtland Sutton and Calvin Ridley.
Closest call: Emeka Egbuka (player_id 12514, proj_season_points 193.2, adp 67 — better ADP than Flowers' 78); I went with Flowers because the projection field, which is what the scoring table pays, is higher, and a rookie-profile WR adds no starting value my roster can't already cover.
⚑ Full PPR (`Reception = 1.0` in RULEBOOK) rewards a high-volume target-earner, which fits a WR projected for ~194 points over other positions available — value(s) not in DATA: 194
Aaron JonesR11 · #84 · RB · conf 0.62full record
With CMC and Bucky Irving my only real backfield, I take the best-value RB on the board in Aaron Jones (proj 178.2, ADP 60 at pick 84) and punt K/DEF to my three later picks where the drop-off is tiny.
Closest call: Jakobi Meyers (proj 193.16, adp 54) — highest raw projection on the board and a real ADP value, but my 2 WR + 1 FLEX slots are already contested by five rostered receivers, so his marginal lineup contribution is smaller than an RB3 insuring a two-man backfield.
⚑ DEF gap likewise small: Philadelphia 149.94 vs Green Bay 143.94 (6.0 points), and roster_needs shows DEF 0/1 and K 0/1 with four picks left, plus the rulebook's round-13 pool narrowing guarantees I can still fill both required slots — value(s) not in DATA: -13
Green Bay PackersR12 · #93 · DEF · conf 0.72full record
With five rosters still missing a DEF and only two elite units left on the board, I lock in the Green Bay Packers as the top-projected defense and take a kicker with pick 100.
Closest call: Daniel Carlson (K, proj 154.87) — the highest raw projection among positions I need, but Team B is the only club picking between 93 and 100 that lacks a kicker (roster_counts_by_team), so waiting on K costs me almost nothing while waiting on DEF likely costs me both GB (143.94) and MIN (139.99).
⚑ roster_counts_by_team shows Team A (K:1, no DEF), Team B (no K, no DEF), Team E, Team G and Team H all lack a DEF; picks 94-99 belong to C, B, A, A, B, C, so both GB and MIN can plausibly be gone before my pick at 100 — value(s) not in DATA: 94, -99
⚑ Kicker replacement cost is trivial here — Carlson 154.87 vs McLaughlin 154.28 is a 0.59-point season gap — so spending pick 93 on the scarcer position maximizes total starter points — value(s) not in DATA: 0.59
Chase McLaughlinR13 · #100 · K · conf 0.95full record
pool narrowedTake Chase McLaughlin, the highest-projected kicker available, to fill the last empty starting slot.
Closest call: Will Reichard (player_id 11792) was the only alternative in `available`, but his proj_season_points of 149.28 is strictly lower than McLaughlin's 154.28 and no other DATA field distinguishes them.
Trevor LawrenceR14 · #109 · QB · conf 0.68full record
Take Trevor Lawrence as the only QB insurance behind Patrick Mahomes, and the highest-projected player left on the board.
Closest call: Tucker Kraft (proj 154.5, adp 90) — the best raw-value non-QB and a plausible FLEX starter, but he is redundant behind Trey McBride and I can still target a TE/WR with my remaining pick at 116, whereas a startable QB is the one position where a hole scores literally zero.
Tucker KraftR15 · #116 · TE · conf 0.76full record
Tucker Kraft is the highest-projected TE left and the only cheap way to cover the one starting slot my roster has zero depth at while also being FLEX-eligible.
Closest call: Cooper Kupp at proj_season_points 168.5 — the highest non-QB projection available — but as a sixth WR behind Chase, McMillan, Sutton, Ridley and Flowers he would almost never crack the 2 WR + 1 FLEX slots, whereas Kraft covers the single-deep TE slot that scores 0 if empty.
