Not sure if this is being implimented this year and i dont think it is........ But instead of ONLY being able to upgrade your players by assigning them with assistant coaches... you should be able to gain atributes by how you are actually using your player in a game... If im managing to score 20ppg with nate robinson shouldent his rating slowly go up? If not here is another idea:
Remember when in dynasty mode they had goals for you to reach IN THE GAME like 10assists with one player, double double etc and you get points, not just to unlock some stupid SHOE lol but to actually improve your team. I think they should bring that back and let you scheduale special practices to improve players if you get a certain amount of task points it makes playing the game so much more fun knowing that if you reach certain goals you get rewarded in some tangible way rather than just unlocking some stupid new shoe color.......
