But with a decent game engine, you don't need a turbo button to control acceleration; all you need is an analog stick to tell your player how hard you want him to to go, and the game will take care of all the momentum and acceleration for you.
Have you played EA's NHL games since they took out the turbo button? NHL '09 probably has the best momentum physics of any sports game out there, and a large part of why it works so well is the absence of the "turbo" button that used to let players instantly accelerate to top speed and fly around the ice like they had no weight at all.
That's the problem in these NBA games: players can skate around the court at top speed with no feeling of momentum or acceleration, unless they happen to have the ball in their hands.
For some reason, these games have decided that only the ball handler needs to be subject to the laws of momentum and acceleration.
Next year's games need to make everyone on the court subject to the same physics, otherwise you get the mess that we have right now, where everybody but the ball handlers can zoom around the court all game long like they're The Flash.
