YouTube star Jake Paul won his second professional boxing match with a devastating knockout against former NBA player Nate Robinson.

The vicious knockout turned Robinson – lying prone on the canvas – into a meme that has gone viral.

But Paul’s bout with Robinson may have over-inflated his confidence as he issued this challenge.

Jake Paul seems to be taking boxing seriously.

He’s been training diligently for over a year, and he dominated Nate Robinson in a fight that ended with a brutal second-round knockout.

However, Paul’s beatdown of Robinson, who had only been training in boxing for three months, might have over-inflated his ego.

Paul now wants to fight former MMA star Conor McGregor in a boxing match.

Not only does he want the fight, but he’s promising to crush McGregor.

Paul said, “The Jake Paul vs. Conor McGregor fight is going to happen and it’s just a matter of when and it’s gonna be legendary and I’m going to win, too. That’s what I want people to really understand . . . I’m gonna dedicate my life to winning that fight because I’m not going in there just to f—ing say I did it. I’m going in there to f—ing f— Conor McGregor up.”

Paul may have bitten off more than he can chew this time around.

Even though McGregor isn’t a seasoned boxer, he’s a highly trained professional combat fighter who knows how to take a punch and protect himself better than Nate Robinson ever could.

McGregor also went ten rounds with Floyd Mayweather Jr. before losing in a TKO.

Beating a 36-year-old former slam dunk champion with only a few weeks of training isn’t the same taking on a professional fighter.

If Paul is serious about his craft, he needs to fight at his level and not overreach for seasoned pros like McGregor.

That said, a fight with McGregor would likely be a huge moneymaker.

It could also spell the end of Paul’s boxing career.
