Joe Louis was pretty much humiliated and bitch slapped by Max Schemeling. Jack Dempsey was knocked out in one round by Fireman Jim Flynn.

They both recovered from those one sided beatings, and ended up pretty decent fighters.

Wilder was always flawed as a boxer, but he has that big equaliser. He will always be that, and he may well have come unstuck earlier in his career (but was well protected). He can come back and will always be competitive.
