A beta site benefits from having one concrete thing it can actually do. For Sportsecon.com, the right starting point is a fourth-down simulator because it sits at the intersection of incentives, game management, and quantitative reasoning.
Why start simple
There is a large gap between a polished public-facing simulation product and a useful first-pass decision model. The current version uses a lightweight expected-points framework, conversion estimates by distance, field-goal success bands, and small late-game nudges. That is enough to create a coherent recommendation without pretending to be a full win-probability engine.
What the beta is for
The purpose of this tool is to support exploration. A coach, fan, or analyst can test a situation, see how the recommendation changes, and quickly understand which assumptions are driving the result.
Over time, the model can become more granular. It can also remain useful even if it stays lightweight, provided it remains transparent.
