i would think wilder would be beaten by pretty much any top heavyweight who is isnt a midget... his punching technique is pretty awful too and no wonder he hurts himself so much :S.. His style is so crap though that combined with his huge reach I would give him a pretty good chance of accidently knocking anyone out :S he can generate an amazing amount of power from nothing a lot of the time. if it goes past 4 rounds though i think wilder would lose to a good heavyweight tohugh.
