Undefeated boxing legend Floyd Mayweather Jr. welcomed mixed martial arts megastar Conor McGregor inside the squared circle back in 2017. "Money" Mayweather earned a dominant TKO victory over the Ireland native within the tenth round of their match up. Earlier in his career, Mayweather faced off against now unified middleweight champion Canelo Alvarez. This time, Mayweather went the distance. The undefeated boxer earned a majority decision over his opponent. Still, taking to Instagram, Floyd Mayweather Jr. has now come forward to claim that he believes Conor McGregor was a more difficult opponent than Canelo Alvarez. Check it out below. "It didn’t matter if Canelo ate his PED steak or not this night, this was by far the easiest fight of my career! Connor McQuitter was a way better fighter than Canelo's cheating ass and I beat the brakes off him too! It takes me 36 mins or less to make $300 million plus. It literally takes me 1 night and 1 fight to make what you might make in 5 years and 11 fights! So really, who's still winning? You do the math!" https://www.instagram.com/p/BpFZ3Xggm6Y/?taken-byfloydmayweather For more MMA news click here.
