Priced like a business
Every player is treated as an asset with a cost, a term, and a market. Moneyballin runs the same trade-offs a GM defends to ownership.
Surplus is the scoreboard
One question runs through every mode: what is this contract, pick, or roster spot worth against what the team is paying for it?
Cap rules, not vibes
Aprons, dead money, void years, and CBT thresholds are the constraints. The tools here make those constraints visible before you make a move.

Player Contracts

Valuation Lab

The core teaching tool: each grade compares current pay with a position-relative market estimate. The model weighs production standing, overall and outside position rankings when available, age curve, and each league's salary market. An A requires meaningful dollar surplus, not just a cheap deal.
