For anyone else that has been nerding out about the ninja headbands like I have... It looks like in the Create a Player screen you can choose band or tie for the head accessory which is nice cause that will allow you to easily change the color just like all the other accessories.
The tied part in the back does appear to be a little too short compared to how the majority of players wear theirs so it will likely require some tweaking. But I do appreciate 2K adding it in and it will be nice to have something to work with.
