Trade Builder & Grader

Build a player-and-pick scenario.

Performance-only gradeBuild a trade

Compare two- or three-team exchanges without contract dollars or cap calculations. Picks are hypothetical selections—not verified current ownership. Unused third teams can stay empty.

Scenario points and limitations

Established players receive max(0, (Projected Impact − 40) × 2) points. Hypothetical rounds 1–7 receive 30, 12, 6, 3, 2, 1 and 0.5 points. These are transparent, illustrative assumptions, not empirically calibrated trade prices. No adjustment is made for contract control, age beyond the impact model, prospect upside, pick position, year discount, conditions or trade protections. Players with insufficient samples cannot receive a grade.

A package is “similar” when each team's absolute net difference is at most five points or 10% of total exchanged points, whichever is larger. This compares scenario points—not actual trade fairness or team fit. Changing a team clears all selections to prevent stale ownership assignments.
