It is confirmed now that the main event for UFC 300 will be revealed during the post-fight press conference of the UFC 298. Yeah, I think so too, that they haven't had confirmations in the backroom for who will be fighting. We'll find it out soon enough though.
Wasn't it said that Conor VS Chendler would be the main event of UFC 300 or did I really read something wrong back then? 
Even if McGregor is able to fight, he's not really a draw of high magnitude anymore. The guy is washed as seen twice vs Poirier. There's just nothing he can do... He is past his prime. :/
What the UFC could do is pay Jon Jones a bunch of money to return earlier than intended to fight Tom Aspinall. That would be a good match up. They should just forget Miocic and pay him a bunch of money too, to stfu. Lol. No one really wants to watch him anyway.
Live in 12 hours... Should be good.

McGregor is washed, finished. As I understood, he wants to gain fame again and at the same time he has new ambitions but you know, coke makes you too confident in yourself and that's where McGregor makes a mistake, he can't become a champion in a new division at this age, especially since he wasn't training and was snorting bunch of coke lines. Dana will use him to make money, he is super happy when he sees Conor. I laugh all the time when I see Dana's face when Conor is there.What the UFC could do is pay Jon Jones a bunch of money to return earlier than intended to fight Tom Aspinall.
