Until I see it done I don't know if I will be happy , 2k has a long history of promising something but then changing course.
Latest report states crew mode is 5 on 5 , with "seasons" and "playoffs" but does not elaborate on what that means. My assumption is it would function like FIFA clubs mode with seasons being like a promotion/relegation system and playoffs like cups perhaps. I would be surprised if that is not full court If it turns out to be decent I hope they have a friendly system like FIFA clubs so you can avoid playing douchebags all the time.
