I've enjoyed reading this thread and debate... I'd like to ask you how you see the hot/cold streaks in this game...
Even when you have 2 evenly matched teams, when 1 goes hot they can go easily on a 15-0 or 20-2 streak..... it is for this reason I wouldnt add more mid-game tactical options + the added complexity for new comers.
I still maintain opening up the training regimes so that teams can create more varied players will lead to more challenging tactical selections (pre-match.)
Yes, you're right, I agree that 15-0 runs happen, but wouldn't it be nice if you could decide before the game, that in case of a cold streak the coach should take a time out and change tactics...And then again, as in real life basketball, it can be the right adjustment, or even make things worse. I would like to feel this thrill to have asked for the adjustments done, instead of letting the game engine just do it.
It would of ocurse make this game more complicated, but you're not forced to use this option: It can be an "advanced" setting. You should be able to choose,if you want the game engine to decide itself what to do, or to take more responsibility in the outcome of the game by deciding what should be done in which situation (before the game).
Your suggestion to create more varied players is already quite well implemented I think. you can train your players how you want, it just takes a long time until you have the player exactly how you want him to be.
