That statistics overlay is inventory, not a service

The numbers layered over a live picture exist because somebody bought the space, and that shapes which numbers you are shown.

The expected-goals figure in the corner of your screen did not arrive because a producer judged it the most illuminating thing available. It arrived because a data supplier has a distribution deal, a sponsor has a branding slot attached to the graphics package, and the overlay is one of the few pieces of screen real estate a broadcaster can sell without interrupting play.

That is the honest description of the modern stats layer. It is inventory. Understanding it that way explains its quirks better than any argument about analytics. Why do certain metrics appear constantly while more useful ones never do? Because the supplier who won the contract computes those metrics, and switching to a rival's numbers mid-cycle would break the sponsor's creative and the graphics pipeline at once. Vendor lock-in, dressed as editorial judgment.

It also explains the strange conservatism of the interactive versions. A broadcaster's app will let you tap for a player's shot map but not for anything that would make a pundit look wrong in real time. The overlay is a product with a marketing owner, and marketing owners do not enjoy features that generate arguments they cannot control.

I would rather the industry admitted this and priced it properly. Data rights are now a real line in a league's revenue, sold separately from pictures, often to companies whose largest customer is the betting sector. When your screen tells you a team has some probability of scoring in the next ten minutes, the underlying model was probably built for a market maker and repurposed for you. The version you get is the slower, blunter one. The sharp version is the thing being sold.

None of that means the numbers are wrong. It means the selection is not neutral, and selection is where influence lives.

Watch what happens during a contract handover between suppliers. The graphics change, the vocabulary changes, and a metric the audience had been trained for two seasons to treat as authoritative simply stops existing. No editorial explanation is offered, because there was never an editorial decision to explain.

The test I apply is simple. If an overlay never once contradicts the commentary, it is not information. It is decoration with a logo on it, and the interesting question is what the logo paid.
