I'm working on that today actually. We don't have player ratings in yet for in air collisions so it's a very simple algorithm that decides if one, both or none get altered and by how much.
What you see in this video is extremely rare in the game right now, which was one of the reasons we captured it.
I'll see if I can get you guys some examples of dunk on attempts that do get altered for some of the next videos so you can see the difference.
What you see here should really only play for a very, very strong player dunking on a very, very weak player.
