Behind the MVP Numbers: Curzan, Heilman and the Measurement Problem of a League

It was 2:40 in the morning in Khulna, the laptop throwing blue light across a table with a cup of tea gone cold beside it. Scrolling through the Match 2 results, my eye caught a column nobody reads — how many times a swimmer entered the water, and in which events. The SwimSwam release naming Claire Curzan and Thomas Heilman as CSL Match 2 MVPs carries a full list of times beside it. What it does not carry is the one thing I wanted: what each of them paid for the position, and what everyone else could not afford.

A results sheet takes five minutes to read. A league match takes three to four hours. Every entry a swimmer makes inside those hours has a price — physical, tactical, and accounting. An MVP label claims to add those prices together, but nobody prints the formula.

What the CSL actually measures

SwimSwam's CSL is a season-long, team-versus-team match series, and that formatting is the real event. At a championship, a swimmer races for time and placement. In a league, she races for points, and points come from finish order, which in turn comes from the triangle of taper, travel and team need. A league performance is a number poured into the mould of team requirement.

This is where the MVP problem lives. At a championship, 'best performance' has a workable definition: time, place, record. In a match-format league, all three are relative. A winning 100 backstroke can rank below a second-place swim in the neighbouring event, and a fourth relay leg can be worth three individual wins in team points. Match MVP selection therefore becomes a blend of published results and match impact — reasonable, but a space opens up between a writer's decision and a formula's decision.

My method is simple, tedious and deeply unpopular: every claim gets a source and a collection date attached to it. Over six months in 2026, sitting in a district public library, I logged 1,100 Bangladeshi swimming results — every national championship from 2026 to 2026, every Olympic universality swimmer, every long-distance race on the Dhaleshwari. What those six months taught me was not about any swimmer. It was a sentence: a single match never tells a story, it tells a curve.

Bangladesh's national 50m freestyle record has improved 1.8 seconds in 32 years. Over the same period, the world's 20th-fastest man improved by 2.4. Read separately, 1.8 against 2.4 looks like standing still. Read together, standing still means falling behind. That habit — reading a number against the curve of the field, not against itself — is the basis of everything below, including an MVP label.

One warning runs through every figure here. A 25-yard pool and a 50-metre pool are not the same sport. The conversion table is a convention, not a law of nature. The more turns and underwaters involved, the more a short-course value inflates. In short-course yards you measure speed in seconds; you measure power in the last 15 metres of a long course. Anyone who survives on turns will be mispriced by any converter.

Curzan: a peak-value swimmer whose price sits at the wall

Claire Curzan's asset is range. Backstroke plus butterfly: two stroke families, four separate events. In a team league format she is the wildcard a coach wants out of the deck — she can be placed almost anywhere and still return a competitive number.

But the column that matters is the one nobody studies: the five metres before and after each wall. Dolphin kick count, breakout distance, the turn itself. In 32 years of my Khulna archive, one pattern holds cleanly — Bangladeshi swimmers lose their races at the walls, both ends. A swimmer like Curzan is strongest exactly where we are weakest. What that strength converts into on a league points table is not stroke quality, it is capitalised advantage.

A professional racing a college meet is herself an institution: training group, sponsorship, taper calendar. For her, an MVP label is not honour, it is valuation. For a teenager, it is honour, not valuation. Same word, two jobs.

Heilman: the number that matters is the slope, not the time

The most contested thing about Thomas Heilman right now is his birth year. Reaching international standard in butterfly as a teenager means two things at once: rare talent and extreme risk. The 200 butterfly is structurally unforgiving — lead at 100m and you are not supposed to be there at the finish. The current world record of 1:50.34 was built on a model in which every 50 gets progressively slower.

What I watch for is fast starts at junior age. A young swimmer's energy-management judgement trails his body by roughly two years. A world-class opening 100 followed by a two-second fade over the closing 100 is a pattern I also saw in a scouting report I filed in 2026 — outside swimming. In 2026 I filed the warning; the market filed it under noise.

Swimming enforces the same rule. Breaking age-group records and surviving at senior level are different tasks. The Khulna archive reminds me constantly that an empty dataset is still data. With junior prodigies the missing list is the one we never keep: the ones who burned at 17 and were gone by 21. A database that keeps only winners cannot forecast, it can only celebrate.

The denominator nobody writes down

Here is the central argument. MVP is a score with no denominator. Points per swim, points per taper, points per dollar — change the denominator and the award goes to a different person. A swimmer who enters three individuals and a relay and wins all of them tops the raw points. But her per-swim return decays through the evening as the body empties. A swimmer who enters twice and posts two personal bests may score fewer points and return more per entry. In league language, the first is MVP and the second is invisible. An award that does not measure per-event return is really measuring availability, not excellence.

Second problem: selection bias. The MVP usually comes from the winning team. That bias is editorial rather than mathematical, and it is understandable — but it means a genuinely outlier performance on a losing side vanishes by season's end. The lesson from my 2026 pond ledger applies directly: I opened the pond ledger and found 412 names the page never counted. That page stalled at 300 followers. It was accurate and it never arrived. An MVP list is the same object — correct but incomplete.

A Bangladeshi read on an American league

Why should a reader in Khulna care about an American college league MVP? Because our swimmers enter through universality slots and theirs enter through league matches. Both are measured in the same events; the cost behind the number is different. A tenth of a second here costs ten years, a district pool and an unpaid coach's evenings. A tenth of a second there costs four coaches, an underwater video analyst and an annual taper plan.

That asymmetry breeds exaggeration in both directions. We treat their success as magic and our failure as the absence of magic. Neither is true. The truth is two economies on one timeline. Swimming has no VAR, but it has the equivalent: the review after a touchpad finish, the referee's ruling on a turn, the two-minute wait of a disqualification — enough time to cool the celebration of a gold-medal moment. The clock decides the time; a human being validates it, and that judgement always lands somewhere in the blind spot of the data.

What I refuse: treating a label as evidence

Now I argue against myself, because I always do it first. The biggest enemy of the MVP award is not the debate about who deserved it — it is using the award as proof. If a swimmer is MVP, her team probably won. If her team won, the times were good. That is correlation, not causation. Treat an award as a cause and it will expose you as a fraud one season later. In 2026 my lesson was that a correct number and a good story are different plants; they do not grow in the same soil. An MVP list is a story's caretaker, not an accountant's.

Still, the strongest counterargument belongs in my own sentence. The label does work. In American college recruiting, a season MVP list enters the next season's conversations and reduces verification cost. Nobody can be everywhere; a label is the cheapest available sample. I accept that. But a cheap sample is not a reliable decision. I am not saying the award is worthless. I am saying it is a filter, not a microscope — and most people use it without knowing which.

Forward, with a date

My prediction, with confidence and conditions attached. If Heilman's second-100 fade in the 200 butterfly narrows over the next two seasons — closing-100 loss under a second and a half — then sub-1:53 long course becomes the natural outcome inside the 2028 Olympic cycle. Confidence: 65 percent.

Curzan's conditions are different, because her issue is not timing but range. If her per-event return holds across three events, she is worth more in a team culture than in individual competition. That is not a weakness; it is the name of specialisation. Update trigger: when Match 4 split data lands, I will re-run this.

When the number returns to the screen, we owe it one question at least: the names we are reading — whose names were left out beside them?
