So basically nobodies and there is no reason to watch.
They sold out the venue and it's reported at over 750k buys, prob more by now.
I have seen Logan Paul in the gym awhile back, the kid has so-so skills for his experience level, his wrestling is def above avg. But then again, I believe he was a HS State Champ, or a State Qualifier, in Ohio in Wrestling, so I guess the Wrestling skill set is to be expected. He and his brother have been hiring Pro Boxers such as Mosely, Judah, and a few others, to help them prep for this event.
I believe KSI has been training RVCA and Wild Card, to what extent though, I have no idea. He has also got some rounds in at Mayweather's gym, and has done some MMA grappling with Bisping. I don't know what his skill set levels are at though.
I am 40, and still think it's crazy that YouTube and social media literally can make someone a "celebrity", but I bet if the UFC had put Logan Paul on a card, instead of CM Punk, the card would have did above avg ppv numbers for the UFC.
