You already know the story. Here is how we checked it.

How do we know?

Era Theory does not start with a score. We start with what happened, compare the whole eras, write down the rules before judging them, and then try to break our own answer.

The goal:A casual fan can follow the conclusion. A serious fan can audit exactly how we reached it.

Quick version

Five steps. That is the whole idea.

1

Define the eras

Decide exactly which seasons belong to each leader and what each one inherited.

2

Collect what happened

Seasons, playoffs, quarterbacks, drafts, trades, coaching, star players and major injuries.

3

Compare the important parts

Winning matters most, but one stat cannot explain how an organization succeeded or failed.

4

Try to break the answer

Change the priorities, remove categories and run alternate versions of the model.

5

Publish the story and the proof

Fans get the plain-English answer. Anyone who wants more can inspect the sources and rules.

What did we actually research?

Much more than wins and losses.

The 401 count only includes the main row-level evidence registers once. It does not inflate the total by counting dashboards, summary tables, charts or repeated conclusions.

28

Seasons

Every completed Colts season from 1998 through 2025, including regular-season and playoff outcomes.

13

Major quarterback decisions

From Manning and Luck to the post-Luck succession attempts.

28

Draft classes

Every class in the period; recent classes are tracked but not forced into mature grades too early.

110

Notable draft picks

Stars, misses, useful contributors and developing players used to understand how each class really worked.

58

Major roster moves

Trades, free-agent signings, extensions and premium-resource decisions.

42

Coaching records and major decisions

28 coaching-season records plus 14 major coaching or governance choices.

107

Elite player-season events

All-Pro and Pro Bowl-level seasons used to see who actually built and retained high-end Colts talent.

15

Major adversity cases

Seasons where injuries or availability problems seriously tested the roster.

How does the score work?

Seven football questions. Results matter most.

The public score is a weighted comparison of seven parts of running an NFL organization. The research category names are shown too, but you do not need the jargon to understand what each one asks.

Fan questionResearch categoryWeight

Show the exact construction behind those categories

Team results: 70% winning percentage + 30% winning-season rate.

Postseason: playoff, division-title, deep-run, Super Bowl-trip and championship rates.

Quarterback: continuity, intended-starter share and multi-year succession stability.

Draft/development: 65% mature draft-class index + 35% player peak/homegrown-core index.

Roster resources: move quality, positive rate, failure avoidance and premium-resource hit rate.

Coaching: 40% continuity + 60% coaching-phase quality.

Adversity: preparedness, replacement execution, result preservation and adjustment.

Published result70.5

Bill Polian

Ryan Grigson 61.1 · Chris Ballard 47.8

If we change the priorities97.7%

Polian still wins

Across 200,000 unrestricted random-weight models.

If every category must still matter100%

Polian wins again

Across 100,000 bounded models with each category between 5% and 35%.

Can someone else win?

Yes. Ballard wins a deliberately narrow model that only cares about drafting and roster moves. Grigson wins a narrow roster-plus-adversity model. That matters because it proves Polian is not hard-coded to win; the result changes when the definition of the job genuinely changes.

Where does the information come from?

Every core evidence row has a source.

We prefer official or primary sources for organizational facts, then established statistical databases for historical records. Judgment calls stay labeled as judgment calls.

Authentic imagery

Real people and historical moments use rights-reviewed real photography with creator, license and modification records.

Why isn't the entire workbook public?

The organized 28-tab research database is kept private so the underlying research asset is not simply handed away. Public transparency comes from publishing the evidence counts, formulas, source policy, exclusions, limitations and a model readers can test themselves.

What can't this project know?

The model has limits, and we show them.

No private team information

We do not have scouting boards, medical files, ownership discussions, contract negotiations or internal coaching evaluations.

Recent drafts need time

The 2023–2025 classes are tracked but withheld from mature class scoring until enough NFL evidence exists.

Future draft capital is unresolved

The Sauce Gardner trade remains recorded but unscored until the on-field return and future first-round opportunity cost can be evaluated fairly.

2026 is still happening

The historical verdict stops after completed 2025 seasons. Active 2026 evidence does not move the published score yet.

Some categories require judgment

Draft, transaction, coaching and adversity grades include evidence-coded judgment. The rules are explicit so people can disagree with them.

300,000 tests are not a truth probability

The simulations tell us whether the ranking is fragile when priorities change. They do not mean Polian is “97.7% objectively correct.”
