Methodology

How the simulations work depends on the league system being modeled. The U.S. pro leagues operate as closed systems with drafts and fixed playoff brackets. European football runs on promotion and relegation across multiple tiers. NCAA sports introduce conference realignment, large team pools, and tournament-style postseasons. Each track below covers the methodology specific to its competitive structure.
