#79 - I Thought I Solved Player Longevity — I Was Wrong

AI promises to compress months of work into minutes. Sometimes it delivers. Sometimes it delivers an answer that looks right — and isn't.

This episode steps away from the usual sports vision topic to share a behind-the-scenes story: a week spent building, validating, and then dismantling an AI-driven model that appeared to predict Major League career longevity from vision testing data.

The dataset was real and substantial — 14 years of consistent testing, 14 MLB organizations, 6,006 professional players, and likely the largest vision database of professional athletes ever assembled. The model came together quickly. Early external validation looked convincing. The breakthrough seemed real.

Then came a one-hour conversation with one of the smartest executives in baseball — and the model fell apart.

The flaw wasn't the AI. It was the assumption that AI alone could navigate selection bias, framing, and the right statistical questions. AI is going to reshape sports science the way the GUI reshaped computing — but only when it's paired with human skepticism, domain expertise, and the willingness to challenge a result that looks too clean.

IN THIS EPISODE, YOU'LL LEARN:

• Why an AI-built longevity model can look accurate and still be fundamentally wrong
• How selection bias hides inside even the largest professional sports datasets
• What MLB front offices actually need from vision data before they'll act on it
• Why human judgment — not raw compute — is the limiting factor in AI-driven sports analytics
