I had asked about this in the First Access Forum and had received some tips but now I can't access it so I will ask again.
I would like to sim some seasons in Sandbox mode to develop history for the league prior to entering as a player and taking control of a team. How do I convert the league files to Career Mode? I see a button to do that but after the update to career mode is complete I don't seem to be a coach of the team I am selecting to control. Sorry for being dense but it didn't ask me to create a coach and I am not sure I am controlling the team as I had hoped.
