as for martial arts even mma guys say they are useless. doesnt matter what you do , you need to actually go and fight people in real fights and nearly all top boxers and also mma fighters did this as they were brought up in **** holes where fighting was survival.
Would love to see Tyson and Liston together in Prison beat the crap out of bullies. And No , i dont think it is real , do not think that there is something in Prison that stops a professionel boxer. Particularly a Tyson.
James Stabler (UK HW and future ATG) runs prison when he goes inside. The guards can't handle him, regularly taking 7 of them to restrain him. To stop him getting angry they've resorted to cooking him steak every night. The other month one of the screws overcooked his steak (James likes it medium-rare) and that was it, he went off his nut. In the end the screws had to unleash the police dogs, but Stabler ended up knocking all the dogs out.
It amazes me that people forget this. Most boxers throughout history are the same as the guys in the prisons....only better trained. People act like Tyson was just some hardnut 'boxer' and outside the ring he was nothing? FFS Tyson was arrested 28 times by the age of 15, most people probably thought of him as their messiah when he went inside. Tyson himself said he loved going to prison when he was younger, he said it was almost like a class reunion.
