Jones would be winning the fight very easy but Wilder would catch him at some point and KO him brutally.
Wilder as a very powerful heavyweight punches harder than anyone that ever knocked Jones and Roy never fought anyone with the reach like Wilder`s, Deontay would have knoced Ruiz out in 1 Rd, Jones never proved he was a good heavyweight and was caught at times by Ruiz and Wilder`s punches are far harder to evade than Ruiz`s, Fury would have been hit a lot less by Ruiz than Roy was also that night, an overated operfprmance I feel, Ruiz was nowhere near Wilder`s level.
Wilder would outjab Roy because of the amazing difference in reach, it would be like Ray Leonard v Hearns at welter in `81
Roy slips 99% of Wilder's windmill right hands, but it's that 1 that finally lands that matters. Up huge on the cards, Roy takes a nap.
