i'd like one major change, the ability to ACTUALlly COACH your team, This would give an advantage to the more active managers.
you can call timeouts when you wanted and during those timeouts you can make substitutions you see fit as well as change the tactic tof it your lineup out on the court. Example you see your shooters are ice cold, you switch from run n gun , to say look inside or something like that. Or at least be able to place emphasis on the player you want to have the ball in certain situations.
I know its a long shot but just a thought. It would add so much more to the game and become more of a coaching game instead of just an ownership position
