You can't choose to hold the Draft over if you want to use a custom roster.

well, can i simulate first seaseon with normal roster and than change the whole roster with your new update?

Yes, you can.

well how ?

Simulate the first season, save your game and then copy the database files from the roster update to your Dynasty save.
