I think about it this way...being at HW, Tyson doesn't even have to be Danny Green level as a fighter. He would land and it would not likely end well for Roy.
Good question. I have RJ wide UD. Tyson hasn't fought in years. He is what? 44? Just because he recently lost some weight does not mean he has any business fighting. I don't see Tyson landing anything flush. Jones will see the big punches coming and roll with them. Tyson is not a big HW to begin with.
it took me all of 3 seconds to finish the poll. The first punch Tyson lands to the body of Roy, and Roy's night will begin to become a little less enjoyable. Tyson isn't as fast anymore, but neither are Roys reflexes. And I can't imagine Roy being able to hurt a guy with a monster chin for Heavyweight.
