I hope Conor just pulls up and beats the shit out of him.— Nolan Cooper (@Juice_47) December 15, 2020With the online community rallying behind Nate Diaz and Conor McGregor, it seems like a match-up with either of the two is surely somewhere on the horizon.More importantly, as Jake Paul finds himself on the warpath with MMA stars, it begs the question: has he bitten off more than he can chew?
