And it seems, Tyson is not anymore for the money here. So he doesn't want this exhibition fight anymore. He realized, if he will push thru, he's like been milking by these Paul brothers and he doesn't want that to be his last legacy. So yeah, good for Mike Tyson to stop this kind of entertainment in boxing. He's pretty much settled already with his life.
It was indeed a good thing to see that he somehow managed to overcome his past mistakes, I really thought that it was his end after he got addicted and some other issues that he wasted so much money. And now he is trying to rectify everything by doing some good cause and building business which is a successful especially his Marijuana venture and other business that he's handling.
Yes boxing was his passion but he also knew that his days at the ring and he have no troubles in money now.
