Ramone said the player editor is the same as last year. This could be one of the following.
1. It's just locked for the stream (they are in crunch time now)
2. Equipment brands may be locked for players.
Example Puig wears Nike, so in the game he may only be able to wear Nike. We can't change it Mizuno or any other brand.(I could be wrong though) I know it's like this in 2K15.
3. Nothing but a coincidence.
