tyson is a boxing historian. a true student of the game. not many no more than him the rich history those belts represent. therefore, he is wrong.. those belts are not garbage. his behaviour and pissing his multi-million fortune away is what's 'garbage'
I have Tyson's bio doc so i'll comment on why he behaved like the animal he did.
It sold fights! He said crazy, stupid things because it drew attention to him. This is before you could stream fights online, so you had to buy it. Fucking guy was one of the most popular athletes on earth. Did he rape that girl? He says he didn't, but so does every other convicted rapist. That aside, his biting Holyfield's ear was in retaliation to repeated headbutts. He talks a lot of shit, but so did Ali, so does Mayweather. They all are/were great champions.
He changed his demeanor after converting to Islam and having a bunch of kids. He outgrew his flashy lifestyle.
