So before Tyson worked for Don King, I learned that he had wiped out all his fighters. It wasn't intentional, just how it happened. So perhaps this fueled Don's desire to make money off of him, then rob him in the end and make he wish he was dead. Don King was a gangster.
At 40:40 into this footage Holmes complained about Tyson throwing elbows, headbuts and hitting after the bell. So he said he didn't see a gentleman in there, he saw a beast. So if he wants to be a beast he's gonna have to go in there with a beast. At that time Holmes was saying he would "humble" Tyson, Holmes may have been one Don Kings men.
