You are ignoring the things that most educated people realise
This was an exhibition fight. Floyd fought it like a sparring march, he adopted a totally different style for this fight because he didn't take it seriously.
The fact Floyd still comfortably beat the younger much larger opponent, at 40 years old in the midst of his retirement, really shouldn't be lost in an sane person here.
Floyd basically dicked about in that fight. Watch him smile and laugh in the first few rounds. He clearly felt Conor had nothing for him, and he was absolutely correct.
The fight was a sham. Mayweather didn't even bother boxing him.
Conor isn't a terrible boxer by any means. He has excellent hands, but he should count himself lucky Floyd didn't adopt a strategy that might have embarrassed him more.
Everyone should just see that "fight" for what it was and move on.
