You can only create a MyPlayer.
But there are only 23 options for faces to choose from. (ie the faces are the 2K development team)
You use your same MyPlayer to play in both Career mode... AND MyGM mode.
So sometimes your MyPlayer is on the court doing crossovers, or behind a desk crunching numbers. Lol.
Agreed, it doesn't make any sense.
It was a very rushed development process, is the only thing we can conclude.
