How accurate is Rigorlytics at
projecting NBA contract value?

Ten 2025 free agents were run through the Rigorlytics fair market value model before they signed. This is what the market actually paid them, and what the gap says about how contracts get priced.

Methodology
How the projections were built

Each free agent received a three-tier projection: a risk-adjusted floor, a fair market value baseline, and a ceiling reflecting market upside. Average annual value was the primary metric because it normalizes across contract lengths.

Fair market value is the benchmark used throughout this study. A signed contract landing within 10% of that figure is fair to both sides. Outside that band, one party captured the surplus.

Results
Same deal, two verdicts

A contract that looks like an overpay to a front office looks like a win to the player who signed it. Both columns describe the same number.

Where the model held
Clear roles priced accurately
Ty Jerome landed within 7% of projection. Defined rotational role, no scarcity premium, tempered postseason impact.
Direction was correct on every signing. No player the model called cheap signed expensive, or the reverse.
The mid-market band between $10M and $25M behaved close to expectation.
Where it missed
Context the model cannot see
Positional scarcity was undervalued. Two-way wings and veteran guards drew premiums the model did not price.
Team urgency is invisible to a valuation model. Sacramento overpaid after trading De'Aaron Fox.
Non-basketball risk is not modeled at all. Malik Beasley's market disappeared entirely.
Finding
The 2025 market ran hot for scarce roles

Six of nine signed contracts transferred surplus to the player. Only one landed inside the fair band. That is a decisively player-favorable market, and the pattern in the misses is consistent: box-score production explained less than role scarcity, playoff translation, and how badly one specific team needed one specific archetype.

Every overpay traced to context outside the numbers. Every accurate projection came from a player whose role was unambiguous. Valuation models estimate the market reliably, but urgency, leverage, and risk tolerance explain the variance.
