Yes. Absolutely.
Some of ya'll are tripping so hard for the sake of being prideful.
First of all ya'll gotta think of the context. It probably took Chris a full second to process what even happened. No one expects to get smacked in the face on stage at the Oscars. You can see his right hand ball up into a fist and by the time he registers what happened, Will was already walking away.
Will is way bigger than Chris and knows how to box. Chris has admitted in specials before that he can't fight and knows when to back down. If Will had just kept assaulting him then sure, he would've probably tried to defend himself until security made it to them.
The Oscar's is damn near the last place on earth where anyone in the building expects a physical confrontation between 2 of the participants.
It was like one strike of lightning and then it was over as fast as it started. Chris would've been stupid to escalate it...it would've looked bad and he would've gotten fukked up.
