I once did the same thing with LeBron.
He dunked, defender fell down and got called for the foul. LeBron then stared at the crowd in the baseline then spread his arms, like his chalk ritual, and shouted similar to
this. I could even hear the shout in the game. Later did I realise it was his 100th point (I was slider testing).
I cried when I saw him do that, been a long time since I saw a lively expression in a basketball videogame.
Gerald Wallace also tends to fall down and roll on the floor a lot when I use him to go hard to the basket. He falls down and rolls backwards, making it look like he might snap his neck any moment.
