I dare say he beats both of them. As well after he beats Wilder he forces him into a gimp suit to be part of his entourage.
The odds would definitely be in Lewis’ favor but not to the extent many think. 70/30 in favor of Lewis with the chance of him getting his brain shut off by one shot. Happened to him twice at the hands of guys with about the same pop as Joshua/Wilder. Or at least close to it. A worse H2H matchup for Joshua/Wilder would be prime Vitali. Iron chin, smarter than both with enough power to stop both.
Lewis would be too smart for both of them. Both would have a punchers chance, Wilder more so because of his unpredictability. But my prediction is he would get both guys out early.
