I know you're being tongue-in-cheek but it's flatly false that Wlad hits 5x harder than Tyson. He hits somewhat harder, without getting them both on the PunchKube or whatever it's called we don't know how much harder, I'm inclined to think that Wilder gets up.
They sparred often early in Wilder's career which explains why Wilder didnt want to fight even an old version of Wlad.
