Adamek would get knocked out. The guys that would truly test Wilder are Haye, Thompson and the Klits.
Adamek is so underrated here. He's no Klitschko but beats most guys at HW and would be a tough opponent for everyone else to beat.
Haha if you would ask me in the beginning of 2013 I would say Adamek for sure but Wilder acually stepped up quite a few levels since then. I'll throw in a wilder KO in there.
the problem is wilder telegraphs his left hand before he throws the right, this gives a good fighter indication that the right is comming, and he always finishes fighters with the right, that why i feel he needs more punches in his arsenal so fighters cant see the right, i can see adamek going in and out avoiding the right and taking wilder in deep waters. if adamek survives the first couple of rounds he may drown wilder in deep water.
a boxing lesson. slow chopping of a big tree. In all seriousness it would be a carbon copy of Micheal Grant fight.
