1. I believe so yes. The post moves are similar to other dribble moves in that they use a combination of the left and right sticks.
The controls are slightly different depending on whether or not you're in triple threat.
2. I'm not sure what the box out controls are as I don't believe they are complete. As for rebounding, the left stick controls the direction of the jump, and the timing of the jump is controlled by pressing up on the right stick.
The player will automatically track the ball while in the air and attempt to catch the ball using layered animations on the upper body.
The allows the player to adjust to changing situations while in mid air.
A huge improvement over last year.
