Mike Tyson 'I'm gonna **** you till you love me you .....' whilst on the other end of the spectrum we have Anthony Joshua doing that fake loud laugh like he did when he did recently in that grand opening in Amsterdam. Boxers need a fear factor personality, Mike wanted to kill his opponents, Ali confidently claimed he's the best in the world, had such a strong influential personality who spoke his mind straight. All these guys were real, they had killer instincts and were just better boxers. Wilder has ridiculous power and is pretty fearful in the ring when he literally chases his wounded opponents and puts them in stretchers but he's not really someone to take serious because he's just acts like a typical American ghetto thug, rather than a one man army who will murder anyone who looks at him the wrong way (i.e. Tyson). His staredown with Fury was pretty sick tho haha.
The main reasons I think are:
1)
I believe political correctness is playing a huge part in this too because you can't say anything nowadays without the half of twitter getting offended, just ask Tyson Fury. Tyson Fury belongs in the previous era with a personality like his and if he was given more media attention, he'd have a much bigger fan base. Everything is offensive now
2)
Money which is sort of stemmed from reason #1. Everything is about money, everyone acts fake and puts 'likeable' personalities on (especially AJ) to get sponsorships, viewerships etc. Boxing is about business now rather than about real 1 on 1 wars.
