Blocks of Evidence: The Null Input and the Integrity of Cricket Analysis

Half past seven in the evening. A laptop lies open on the work table at my Mumbai home, a cup of tea cooling beside it. On the screen is an analysis result — every field empty. No title, no source, no information points, no team or player name. Just a grid stamped N/A and insufficient information. I have spent thirty-nine years working with scorecards, clips and pitch coordinates; habit tells me that when you get a result like this, the greatest temptation is to fill the empty cells with your own assumptions. To a busy cricket writer, an empty cell is a terrifying invitation — plant an imagined story and the reader will never notice, and the likes will come.

I did not plant anything. Because the thing called analysis is not, for me, a matter of emotion; it is a matter of arithmetic. And the first condition of arithmetic is to admit that what is absent is absent.

The framework open in front of me has eight dimensions: format and match analysis, player technique and data, team landscape and ranking, league and commercial ecosystem, rules and governance, risk, public narrative, and industry transmission. Each dimension carries its own sub-fields — format (Test/ODI/T20), venue, dew, DLS, the luck of the toss. Without this context, any conclusion in cricket is meaningless. Take one example. If someone writes that a batsman averages forty-two and is therefore in form, I immediately ask: in which format? At home or away? On what pitch? Against which bowling attack? What is the gap between his strike rate in the first ten overs and his strike rate in the last ten? Without those answers, the number forty-two is a neatly arranged lie.

And in the input now before me there is no format, no team, no player, no date. It is not even certain that the input is about cricket at all. To keep the analysis running in this state is nothing but imagination. This is exactly where the principle of source transparency does its work: every conclusion must rest on at least one information point, otherwise the conclusion is not data but guesswork.

This is where the idea I call the chain of evidence comes in. Recall the core mechanism of a blockchain: each new block carries the hash of the previous block; if someone alters a block in the middle, the whole chain breaks and the forgery is exposed. The rule is exactly the same for cricket analysis. Every claim is a block. This bowler's economy is six point eight — that is one block, but its parent block is: which format, which phase, which venue, how many overs. If the parent block is empty, the new block dangles — it has no foundation. Today's analysis result has every parent block empty. So the chain cannot even begin. And that is the correct answer.

An analysis that makes a bigger claim than its input is not analysis; it is advertising.

I have been trying to build this chain for a long time. In 2026, while on the coaching staff at Mumbai City FC, I spent fourteen hours analysing our 2-0 ISL defeat to Bengaluru FC, breaking down our failed high line across twenty-two clips. From that work I wrote a 1,200-word tactical thread on Twitter, with pitch coordinates and passing lanes; it reached 45,000 impressions. The tactical thread started in 2026, and my sentences learned to press — but that pressure has always been applied to data, never to assumption.

My biggest lesson from football came at the 2026 World Cup, when I was writing daily tactical reports for a Mumbai-based sports data firm. In France's 4-3 win over Argentina I tracked Mbappé's seven dribbles and two goals, and saw how Didier Deschamps' 4-2-3-1 exploited the gaps in Argentina's 3-4-3. In that match I found the match in Mbappé — speed, space and decision window, all three at once. But before using this analogy, one condition must be met: state the mechanism first, then the example. The mechanism of Mbappé's runs — creating space, timing, the decision window on the final pass — can be translated into cricket's powerplay, middle overs and death overs. In the powerplay, the space left open because the fielding circle is pushed in is much like the space opened in front of Mbappé. But to transfer it, the data of both formats must be in hand.

Another pillar of the chain is sample-size patience. I always speak in fractions. If someone says this bowler is lethal in the death overs, I ask — how many overs? How many balls? At how many venues? Drawing a conclusion from three overs across three matches is not a conclusion, it is coincidence. In cricket, small samples are the biggest trap, because a single over in a T20 can turn a match, and our brains turn that single moment into a rule.

Venue geometry is another pillar. The same spinner who thrives at Wankhede will not do so at Chinnaswamy — boundary dimensions, wind direction, grass on the pitch, all change the arithmetic of space. This is why my playbook gives venue its own exception field.

One more thing I see again and again in this chain — the use of very young players. A twenty-two or twenty-three-year-old's body is not yet fully formed, yet he is thrown into senior rhythms, back-to-back matches, death overs. The data will say he is in form, but the data will not say how tired his hamstring is. So I keep age curve and workload in two separate columns, and decide by phase.

Now back to blockchain. Blockchain and ledger technology have already entered the cricket ecosystem — fan tokens, digital collectibles, contracts on smart contracts, ticketing. The appeal of this technology is not merely modernity; the appeal is immutability — once a record is written, no one can go back and change it. Cricket analysis has its biggest problem in exactly this place. Once a false claim is published, it enters the chain of social media, then everyone cites it and writes it again, and three months later it stands as truth. If a blockchain ledger can stop forgery, then an analyst too should keep a ledger of his own claims — on what date, from what data, I reached what conclusion.

A false claim is not one bad piece of writing; it is poison for the entire chain.

But this is where the biggest blind spot hides, and it is not in the data — it is in psychology. During a tournament the pressure to publish is immense. After every match a new hook is needed, a new story is needed. Handed an empty input, most analysts do not admit that the data is missing; instead they choose the smoothest narrative. In my experience the danger is right here — we fill the empty cells with obviously it will be this, and then quote that assumption again, citing our own earlier analysis as the source. In this way a wholly imagined chain is erected, whose very first block is fake.

The second trap is reputation-led narrative. When we see a big name, a big fee or a big legacy, we drop the fit check and write the story. Yet the real question is always the same: at this venue, in this phase, in this matchup, will he deliver? On my table there is a playbook, and it is arranged not by a player's name but by match situation. In a zero input, this playbook is also unusable, because every page of it demands a specific context.

So today's decision is not a defeat; it is a correct null result. A null result is still a result — and often the most honest one. The next step is clear: run the source article through Stage-1 again, check whether the information-points field is populated; do not run this analysis until at least three concrete information points, a format and an entity are in hand. A chain begins with its first block; and if the first block is empty, all the rest of the arithmetic is void.

I will watch the next match with different eyes — not looking for a story, but looking for the parent block.
