What this site is

A trade tool that actually plays by the rules.

Most NBA trade simulators check salary matching and call it a day. Hardwood Machine runs every proposal through the full 2023 Collective Bargaining Agreement — the first and second apron hard caps, Base Year Compensation on recently re-signed players, the poison-pill provision on extended rookies, the Stepien Rule, and the seven-pick rule. If a deal is illegal, we say which rule broke it.

Every proposal is graded per team on seven measurable components: on-court value (VORP), an age curve, team fit, contract surplus, accolades, star power, and box-score trend. Picks convert to units on a Kevin Pelton–style curve, adjusted for protections and swaps. When a real ESPN trade grade matches your proposal, we show it next to ours as a sanity check.

Read the full methodology, the CBA guide, or the glossary if anything on the site uses a term you'd like defined.

FAQ

Common questions

Is Hardwood Machine free?
Yes. Four free daily NBA GM games — no account, no login, no paywall. Trades, challenges, guides — everything is free to use.
What are the four games?
GM Challenge (fix a real front-office crisis under the CBA), Theme Squad (draft a 6-man legends roster to today's theme), Trade Machine Challenge (build a CBA-legal trade and see who says no), and Trade Finder Game (pick the best deal the engine surfaces for your player).
Does the trade machine actually enforce the CBA?
Yes. Every proposal is checked against 2023 CBA salary-matching tiers, first- and second-apron hard caps, Base Year Compensation, the poison-pill provision on extended rookies, the Stepien Rule, and the seven-pick rule. If a deal is illegal, the tool names the exact rule that broke it.
Where do the salaries and rosters come from?
Rosters come from the public balldontlie API. Salaries are overlaid from public league cap sources and ESPN's published cap sheet. Draft-pick obligations are tracked manually against public reporting.
How is the grade calculated?
Each team's grade is a weighted sum of on-court value (VORP), an age curve, contract surplus, team fit, accolades, star power, and box-score trend. Picks are valued on a Kevin Pelton-style curve. Full details are on the methodology page.
How often is the data updated?
Live rosters and salaries refresh from source APIs every few hours. Draft-pick obligations are updated manually after any real-world trade that changes them.
Are you affiliated with the NBA?
No. Hardwood Machine is an independent site. It is not affiliated with the NBA, the NBPA, ESPN, or any team.
