Mac Jones's latest usable row shows participation but no usable attempt volume. That is too little to establish a role. FairPlay's strongest scored input is roster status (100), while production is the main limitation. The usage record can test that read but cannot verify an external price or future outcome.
A second verified row that materially changes attempt volume and passing efficiency from Week 9 would test whether Mac Jones's latest role is repeatable. Separately, a material production change or a different market-proxy/production-model gap would require a new FairPlay read.
Mac Jones is age 28, with a career-window input score of 94/100 for QBs.

Historical production, opportunity and efficiency are normalized within the QB statistical group. The market proxy uses the full player pool; career-window and draft-capital inputs use their own scales.
Normalized model input scores, not probabilities. The production model uses completed 2020–2025 NFL seasons. The current-season usage file is a separate evidence layer. The career-window and draft-capital scales are not empirical percentiles.
Career-window input is the strongest part of Mac Jones’s current profile at 94/100. Historical NFL production input is the clearest source of downside at 59/100. For trade decisions, compare that strength-and-risk mix with your roster timeline rather than relying on the overall value alone.
