What choosing Centre-back means
Copero does not simulate formations, line-ups or individual match actions. Position defines the starting profile, calculates rating with its own weights and adjusts season-level statistical production.
Which decisions appear
Every position shares the same event set: academy development, training, contracts, transfers, injuries, media pressure, international duty, finals and retirement. Position can change the numerical outcome, but does not create tactical events absent from the engine.
How to compare the role
Use daily challenge to reduce seed variation, or play two careers in the same mode with different positions. Compare peak rating, goals, assists, trophies and final score; do not treat guide figures as guaranteed outcomes.
