Don't worry about selling, you won't get anything for the players. But you should fire:
Dakila Matillano
Sumaydeng
Saclote and...
Pacaña
Train Jaume Robert and Eric Medalla, they're the only to that are probably worth it.
Build seats in your arena. Upgrade bleachers and lower tier.
Judging by salaries; I'd say play motion offense, and M2M defense.
