I am very very VERY confident that Do Bronx would have little trouble putting Conor on his back.I got conor, I don't think olivera can take him down. but if he can, it is over for conor, olivera is more vicious on the ground than khabib.
I'm not even and Conor fanboy, but even I know that would be a massacre. Conor would KO him in round one. In the words of Corey Anderson, there are levels to this.
