I opened a blank spreadsheet. Thirty-four columns, two thousand rows, and every cell empty. That day an analysis pipeline handed me a report with no title, no source, no information points, no identifiable entities — just line after line reading "insufficient information, cannot assess." What came back under the banner of deep cricket analysis was not a match story but a confession of data absence.
For thirty-three years I have lived between cricket and numbers. Auditing rice-mill accounts in Rangpur by day and hand-coding an expected-goals model by night, standing behind the stumps as an opening batter in the Dhaka league, then walking back to the scorecard — that back-and-forth has made my eye sensitive to empty cells. But this was the first time an entire analysis returned empty. And that emptiness is exactly what stopped me.
The reason is simple. When a number is missing we say there is no information. In cricket, the absence of information is itself information. Which cell is empty, who left it empty, and why — those three questions together make a detective story. I opened a blank spreadsheet and let the Bangladesh Premier League teach me the language of empty cells.
Some context is needed. It is 2026, and I am forty. I publish a four-thousand-word breakdown of the Bangladesh Premier League season: 132 matches, 3,410 shots, and my own distance-and-angle weights, because no public xG existed for that league. Abahani Limited's title run showed a 9.4 xG gap between their modelled and actual goals. Within a week, three betting syndicates email me.
What that experience taught me was not how to write a match report but how to write a methodology note. Since then every claim carries its sample size, its weighting choices, and a stated error margin. My sentences got shorter, my footnotes got longer, and I began labelling every number as measured, modelled, or guessed.
The Bangladesh Premier League is my data laboratory. Public data here is thin, coverage is uneven, and for exactly that reason it is the ideal place for missing-data forensics. In a league where not everything is measured, the empty cells tell you what nobody remembered to measure and who nobody looked at.
So when an analysis returns empty, I split that emptiness into three kinds. The first is what never happened — no match, no over, no ball. That is true zero; there is nothing to find. The second is what happened but was never recorded. This cell is the most dangerous, because the information existed and someone simply did not write it down. The third is what was recorded but withheld — injury data, fitness scores, the numbers inside certain franchise contracts.
In my experience, South Asian cricket is dominated by the second and third kinds. Look at coverage of a domestic tournament — no data on specific fielding positions, no count of dropped catches, no post-powerplay run rate. Yet all of it happened, ball by ball. Nobody measured it, because the decision to measure is really a budget decision, a prioritisation decision. Who is worth measuring and who is not — that division is written into the empty cells.
Since Russia 2026 I watch Germany twice: with eyes and with PPDA. Across all 64 World Cup matches I logged PPDA and set-piece xG, and before the tournament I published a piece arguing Germany's press had already decayed — their PPDA had drifted from 8.9 in qualifying to 12.6. They went out in the group stage and 40,000 people read it. But my model still ranked them third-favourite, so I hedged the text and lost the argument anyway.
That loss taught me to write on two tracks: a loud public thesis and a quiet appendix listing everything my model got wrong. That appendix became the working method behind every later piece. It also taught me that standing in front of a missing cell and showing arrogance is lying against your own model.
The empty analysis in my hands is the same kind of testimony. When the first stage of a pipeline returns blank, that is itself a diagnostic. It says either the source text never existed, or it was joined badly, or some information got trapped in a filter. In every case the missingness is the imprint of a decision, not mere accident. So I do not discard the null output as failure; I ask which information points should have been there, and who removed them.
Another place I stay careful is labelling. I put every number into three boxes: measured, modelled, guessed. Measured means straight from the field — runs, wickets, overs. Modelled means an index like xG or PPDA, with my own weights hidden inside it. Guessed means the zone where I can write a number but cannot put evidence behind it. Unfortunately, much analysis dresses the third box in the clothes of the first.
In football I have said this many times, and in cricket it holds equally: distance covered and high-intensity sprints are sold as effort metrics, yet pointless running also produces pretty numbers. A batter who faces many balls and settles in raises his balls-faced count while the team's run rate sags. The number grew; the utility did not. This is the beauty of missing data — where nobody measures anything, at least there is less raw material for a false story.
A model is a monastery: you enter to escape noise, then hear it clearer. But the monastery walls also draw a limit. If there is no monk inside, if the information points are zero, the monastery gives you silence, not truth. The empty analysis in my hands was exactly such a hollow monastery.
So I decided not to dismiss this emptiness as an input error. I would turn and ask instead: which information points should have been there, and why are they absent? A cricket analysis is complete only when it carries the format (Test, ODI, T20), the nature of the match, the venue's pitch report, the player's role, the team's ranking, and time sensitivity. Without any of these, everything else stands on sand.
The most contentious example of a missing cell is injury data. A fast bowler's knee, a batter's shoulder — this information is often withheld for the team's interest. Yet when a side fields a player back from an ACL, behind that decision sits a metric nobody publishes. Harder than the body is the question in the mind — that empty room of confidence, for which no spreadsheet has a column.
In a franchise auction, most of what we see is recorded information — six sixes last season, one or two match-winning innings. What decisions actually needed were the cells nobody wrote down: strike rate on difficult pitches, economy in the death overs, runs against spinners at a specific venue. The empty cells reveal what decision-makers truly ignore. When a team buys a batter for a big sum, it is buying a highlight reel, not the data of the situations he has never played.
My hand-coded model was crude, but the missing cells confessed more than the goals. It taught me that numbers and empty cells must be read together. Read only the numbers and we claim, "We know." Read only the empty cells and we claim, "Nobody knows." Read both together and we stay honest: "We know this, we do not know that, and the rest was never measured."
Here is my biggest caution, spoken against myself. My attraction to missing data is my weakness. Stories of empty cells feel good; we imagine ourselves as heroes recovering truth in the dark. But not every emptiness is a deep mystery — some emptiness is just emptiness.
Often information is absent because it was never created — because that match in that league had no coverage budget, because nobody set up a camera, because a domestic game had no crowd. Then "missing" and "withheld" are not the same. Without knowing who collected the data, for what purpose, and over what time horizon, treating missingness as signal means building a false story.
The biggest enemy of my model was never a lack of information, but the confidence built on top of that lack. If a second-stage analysis says "insufficient information, cannot assess," that is the most honest answer available. Dropping in invented estimates and calling it analysis is, to me, professional dishonesty. Chasing the contrarian angle, many of my colleagues reach a point where they forget the phrase "base rate." So before every contrarian claim I ask first: what is the base rate? What is the league average? Only then, if the empty cell genuinely speaks, do I write.
When the stadiums emptied, I started measuring what the crowd used to hide. In cricket, a crowd's roar can make a mediocre performance look grand. When the data is as calm as white paper, you can see which innings was truly extraordinary and which grew large only on the echo of a crowd. That lesson from empty stands taught me: silence is not zero; it is a new baseline with its own residuals.
That idea of a residual matters most to me. When we run a model, we assume that whatever could not be measured is worth zero. But a missing cell has its own weight, its own shadow. In economics this shadow is called observed-but-not-recorded. In cricket it has no name, but it exists. The team that learns to measure this shadow is the team that stays a step ahead in the market next season.
In Bangladesh's domestic cricket this shadow is the biggest of all. The Dhaka Premier League, the Bangladesh Premier League, the National League — coverage varies everywhere. The same player, the same innings, but one match is broadcast and another is not. Every ball of a broadcast match enters a database; an unbroadcast match leaves nothing but the run score. So the model is not measuring who is playing well; it is measuring who is playing in front of a camera. If nobody thinks about that gap before selection, talent disappears into the shadow.
After thirty-three years I carry one lesson. Where there are numbers, I show their uncertainty. Where there are no numbers, I show exactly what was not measured, and why. Emptiness is not a defeat; it is a new baseline with its own residuals.
In the next cycle I will not throw away the blank spreadsheet. I will add a new column beside it: "Why is this cell empty?" Perhaps in a few months it will turn out that those empty cells were the most valuable information of the moment. And the analyst who fears an empty cell is not protecting the data — he is protecting his own guesses.
