A great video from Chris Smoove detailing NBA 2K16 MyCareer and MyCourt:
This year the choice is yours to decide what you do on your off days. You can go to live practice to improve your skills, you can make connections with legends and other players to unlock clothing and animations, or you can spend your time with companies getting endorsements. My Court is a new feature that allows you to fully customize it and invite your friends. You can play them 1v1 or 5v5. It’s essential a private Park or Rec Center. It’s also your locker room for starting up ProAm or My Park sessions!
