Here is what happens.
Nene scores on a great fast break transition and CHI immediately calls a time out. Gortat is on the opposite side of the floor at the Wiz bench and never gets anywhere near the play. Gortat is not getting suspended so forget about that as an issue. That's just silly talk.
After Nene scores, Nene steps on Booker foot first. Then he turn to get up court and his next step lands on Bulters foot.
Butler trying to move up court without his foot able to move gets off balance. Nene left hand moving toward Butler is not a push, its just him getting untangled. If you watch closely, its not Nene pushing Butler that get Butler off balance, its his foot being pinned to the court. You can't move without your foot.
Butler then pushes Nene on the hip and starts coming at him while saying something. That was the first act of aggression. You see it best in one of the last clips of this where you can see Butlers face. He is coming at Nene with a look on his face like he wants to get into it.
With Butler having just pushed him, saying something to him and Butler walking toward Nene, Nene stops to stand his ground. Butler walks into Nene. Nene meets him head to head. Butler then says something else to Nene. Nene after a 3 second stand off grabs Butler and ties him up. First one hand and then two. Which when you think about it makes some sense. You don't want to just stand there and get sucker punched.
They starts to get separated and Nene is backing off while Butler is coming at him. Nene cocks his first for a second but never throws as he is backing up.
Then Nene calmly walks to the bench.
Now before anyone call that a homer view of event, go watch and see for yourself. Butler started it. Butler walked into Nene once Nene stood his ground. That said, Nene should have never leaned his head in. He should have walked away after the stand off and pointed at Butler to get the refs to look at Butlers role in the whole things. Once Nene put his hands on him, he made it easy for the refs to blame him instead.
And most likely it never get to that point if a time out wasn't called. Noah and Booker were right there but neither see what is happening because they have already turned to the bench and started walked that direction. Same can probably be said for the refs. Its actually the time out that allowed his head to head to fester a second or two longer then it did. Normally they would immediately have been separated.
