i believe that Jones is most likely the more fit for this fight and if it is done seriously?for sure Tyson will surrender in round 5-6.
I know how Tyson fight in His prime but now?being a Man with Vices ?i don't think he can survive a long fight,His powerful Punch will be taken for granted if Jones lured Him away from court side to side.
Though this is not going to be serious unless Tyson provoke Jones to do so.
When he was younger, most of his fights doesn't extend up to 3rd round which I think was the strategy used by Hollyfield which lasted up to 11th. But this was before. He has to end the fight before he loses gas which makes him vulnerable. With age, I don't know if he can last up to 3rd round if they do this fight seriously. They may have the will to fight but health condition just can't make it there. They both probably have hips problem.
