1. When you press the "steps" button then you quickly press and hold the other button to dunk, like in last two years, but the game uses that animation a bit slower or faster depending on how much did you hold the button, but you should release it before jump. I don't know if you get it.


2. Maintain the actual system but, what you do it's like the animation the guy is going to do, and then use the camera angles used in dunk contests to show the dunk with comments and ESPN logo, like if that was TV. But it wouldn't look like a replay at slow speed, it would be at x1 speed and with that fat man with the camera running behind the player when dunking.
Sorry for my bad-ass English...
