editing playbooks

how can i edit the plays included in the offense and defense playbooks? the only option in-game is assigning buttons to the different plays but theres no option to change the plays. is it another hex edit? thanks.

If there is such a way, basketball fanatics here would already make the plays they've seen which were used by the teams they rooted for.

actually, what im asking for is how to assign the built in plays to a teams playbook.

That may not be possible. NBA2K9 doesnt have a Create Playbook feature -wherein you can just pick the plays you wanted from another team's playbook. But your idea is a graet suggestion for 2k10.

I don't think you can edit them, but you can select a different coach playbook in the Coaching section in your association (I'm not 100% sure in which section)

The closest you can have of assigning almost all the plays available in the game to a team is the standard playbook.

Features-Coach Profiles. There you can change the set playbooks for teams. Same screen as the team tendencies.
