The Delta Duofantasy football, measured

The Quarterback Cliff

The draft decides who plays. It does not decide who is good.

212 quarterbacks drafted 2008–2025. Headline analyses run on the 173 mature 2008–2022 picks: 45 Round 1, 34 Day 2, 94 Day 3.

Cliff or ramp?

Hit rate by pick bucket

No magic round exists — a square-root curve fits best and round boundaries add nothing (p = 0.59–0.87). The practical break: picks 1–64 are a different universe from picks 65+. Small buckets (n printed in tooltip) — don't over-read the 6–10 bucket's 100% on n = 8.

The ladder

Availability is the gate

Ever top-24Ever top-12

You cannot finish top-12 on 13 starts — zero counterexamples in 14 tries. Half of the 12–14-start QBs were startable in Superflex; none was ever a QB1. (12–14 row: n = 14 — suggestive, not a law.)

Act Two

The equality test — once they hold the job, the draft is over

Metric (16+ career starts)Round 1 (n=47)Day 3 (n=10)p

Top-12 rate per starter seasonTop-24 rate per starter season

0 of 48 comparisons separate Round 1 from Day 3 at the 16-start bar; 0 of 48 at 400 dropbacks. Once a Day 3 QB holds a starting job, his season is at least as likely to finish top-12 as a first-rounder's.

Act Three

Rushing is a multiplier, not a substitute

Split at the medians (10.5 rush yds/game, 0.067 EPA/dropback), n = 504 starter seasons. Rushing lifts every efficiency tier — but no amount of rushing rescues a bad passer (OR 0.126, p = 2.2e-14 for legs-over-arm).

The dead zone

Top-12 rate by rushing yards per game

U-shaped, not gated: the 10–15 yds/game band is the worst cell in the study (29.8%) — worse than QBs who don't run at all. Either the offense is built around the arm or the legs; in between is the worst place to be.

Stickiness

Forecast the legs, stay humble about the arm

Rushing inputsPassing / other inputs

Year-over-year Spearman correlation, 338 consecutive starter-season pairs. Efficiency has the largest effect on this season's finish and is the least projectable into next season. Rushing is more than twice as stable (0.864 vs 0.413).

78 tests, six families, each run raw and with log(pick) controlled. College rushing is the only family that survives — and controlling for pick makes it STRONGER. The market has priced everything a scout can measure, and underpriced the one thing that predicts fantasy QB value.

Act Five

The leash — capital buys forgiveness

Round 1Day 2Day 3
Give-up curve: no top-24 through year…Round 1Day 2Day 3
Year 228.6% (n=14)10% (n=20)3.4% (n=87)

Year 411.1% (n=9)5.9% (n=17)2.6% (n=76)

After a bottom-tercile season, first-rounders start again 60.3% of the time against 25.0% for Day 3 picks, and the effect survives controlling for performance (p = 0.0004). Play well and everyone keeps their job. Play badly and only the first-rounders do.

Act Seven

The era turn — the modal QB1 flipped

2008–20162017–2025

Quadrant composition of top-12 seasons. Passing volume did not increase (31.6 → 31.7 att/game); passing got safer and more efficient, and rushing more than doubled (8.96 → 17.7 yds/game, ρ = 0.951 — the strongest trend in the study).

Who to draft

The three rules

Rule 1: Buy the legs before the arm arrives

Rushing peaks youngest (17.9 yds/game under 24) but top-12 rates peak at 26–28 (50.0%). The legs show up first; the efficiency shows up later — buy the young runner while the market prices him cheaply. Corollary: a 30+ QB whose value is built on rushing is a sell.

Rule 2: Pay for rushing yards, fade rushing touchdowns

Stickiness gap, yards minus TDs: +0.403 (CI +0.283 to +0.525). Among top-12 seasons, ~20.8 fantasy points come from rushing yardage and 12.0 from rushing scores. The yardage repeats; the scores do not.

Rule 3: The dead zone is real

The 10–15 rushing yds/game band posts the worst top-12 rate in the study (29.8%) — worse than QBs who do not run at all (42.1%). Do not pay a mobility premium for a QB who is only a little mobile.

A 12-team Superflex league starts 24 QBs every week. The league produces 26–31 QBs a year who hold a job for ten games, and only 10–18 who make it through a full season. First-round QB capital is the only asset class at the position with a defensible floor, and its dominance is increasing (Round 1 share of starter-seasons rising, ρ = 0.588, p = 0.0103). The QB1-to-QB2 gap has not grown — but rushing now supplies 19–45% of it, versus 2–5% in 2008-2010.
