Couldn't disagree with any of these comments, especially with your appraisal of the heavyweights. I think it also applies to other fighters at other weights...and society as a whole. I think it's the world we live in. Everyone has a highlights reel on youtube that makes them look like a worldbeater...regardless of the quality of opponent, and what the rest of the fight was like. Five or six 10 second clips doesn't necessarily tell the same story as watching the full fight. It's the same as Instagram where fiction replaces fact!!!
I think if you put Wilder, Fury and AJ into the heavyweight division in other eras, they would be classed as distinctly average...but they are in the here and now and are pulling in megamoney. I think if you had a 28yo Larry Holmes in this division now, he'd clean house in no time.
Then you have the promoters hyping their fighters up beyond all recognition. It's bananas, but as long as punters buy the PPVs, then it will continue.
Re: the USA question, I wonder if it's about exposure.
Has the move for the big fights going to PPV prevented young potential boxers from deprived areas getting exposed to the sport and hence not 'following the dream to become the next [insert name]'?
