I doubt if Jones would fight again after this...like Spinks. This would be a radically different outcome for Jones than fighting Ruiz and would have probably ended his career.
Tyson would not even need to catch Roy cleanly to KO him. Simply not a fair match for Roy, who was too light in the ass to deal with that type of speed and tonnage. Jones was smart enough to realize that he was not a heavyweight. He only fought heavyweight once, against the weakest "champ" he could find. He didn't want to tangle with the best in the division. Ironically, though, I think he did himself more physical harm by going back down in weight once he had gone up. He should have retired after Ruiz or remained at heavyweight and gone for the huge Klitschko payday. Win and his legend grows exponentially. Lose and he's got a great excuse - 'I'm a former middleweight. So what.'
Jones could not take the shots of antonio tarver.... Maybe he would go 40 seconds against a young tyson....
