Earlier this year, talks of a potential Conor McGregor vs. Floyd Mayweather boxing match had both the MMA community and boxing community fantasizing about the potential fight.

The fight never came to fruition, and ultimately Conor McGregor signed to fight Nate Diaz in a welterweight rematch at UFC 202 on August 20th.

Ahead of that fight, former IBF world champion Robert Guerrero spoke to Fight Hype to explain why the fight is a “slap in the face” to boxing.

“It’ll be a big event,” Guerrero told Fight Hype. “You got all the MMA fighters, you got this, but it’s a joke to boxing. It’s a slap in the face, come on. You’re gonna take the best fighter in the world, and the best MMA fighter… well, was the best, because Nate Diaz put it on him.”

“You got a dominant fighter and this MMA guy. Out of nowhere, you’re gonna give this dude (McGregor) a fight. There’s guys out there like Thurman, all these guys, everybody’s been working their whole career to be in that position and you’re gonna go ‘OK, hey, you MMA fighter, come in here and fight me.’”

“And then you’re gonna break Marciano’s record with that? Come on, dude.”
