Probably round one, Tyson was fast man, I cant believe that he wouldnt find the target at some point in the first round. And when he did Jones would get seriously hurt.
well even ruiz found the target during the first round of their fight and roy was staggered just a little bit, so im gonna guess tyson would be able to do it in 1 round too
well he KOed Spinks (a better and tougher fighter than Roy Jones) in 90 seconds. I suspect he would clip Glass Jaw Roy in about 30 seconds or so?
like sonny liston said anout cassius clay i think 2 1/2 rounds to catch him and 1/2 a round to finish him off
