the dude is not even close to looking like jake paul(at least that is how I see it), the only resemblance I see they have is having blonde hair and a similar looking beard. I don't know why, but why do I feel like this fight was just a stunt to garner more attention for the incoming fight? popular fighters like them getting into a fight like this is very risky and could get in a lot of trouble.
No I don't think it was a fake fight because it obviously happened into an open street. And US federal and local laws are very strict for this kind of things usually, Nate Diaz could be prosecuted for that and put into jail along with being condemned to pay a very high fee. In addition the guy really seem to have finished unconscious, and it's hard to fake a thing like that. Nate Diaz is known to be an aggressive and nervous brawler.
