Yeah, I have no qualms about the Ortiz knockout. The fight was restarted and if you want to hug and fuck around and shit and your opponent doesn't, it's on you. I also get why people hate Mayweather's fighting style. As a long time boxing fan, I just find it technically amazing. I feel it is similar to Steve Vai's music. I don't dig it at all, but I can appreciate his undeniable talent.
Part of me does hope McGregor shocks the world though. Just because Mayweather is a garbage person who deserves to be beat the fuck down. And, despite hating all the hype McGregor fans never cease to spout, he actually sounds like a great guy behind the scenes and as a person. His whole shtick is an act to sell his fights.
