Play as a player mode,
would be a nice addition.
Here you will control a player through a dynasty.
you will start as a rookie in the training camp and show your skills so that teams would keep an eye on you when the draft comes.
For example you choose LeBron, you will assign trainings for him, sign contracts, ask for trade, retire,etc. you can control what characteristics LeBron would have, you can enhance your capabilities depending on your practice sessions. and during the season games you can choose whether you play as player lock on him or play as normal. as for the injuries, when he's injured you can take a week break for a trainer. and heal the injury.
it just came to my mind what about being an nba player.
this could be a great mode for those who's not able to be an nba player.
