Helenius would be a good fight for him, an older fighter who stands straight up and is there to be hit.
Hughie Fury is an interesting fight to me. Hughie has a very good chin and is a B version of Tyson Fury slickster style from the first Wilder fight.
Some stiff. Now that he's been exposed, his managemwnt will put back on the bum train to recreate his bogus reputation as a fearsome KO artist. Then he will fight a top fighter like Fury or Joshua and predictably get KOd again
It will be Ortiz again with the same old narrative of still no one else has dared to fight him, he is the boogeyman of the HW division bull.
Journeyman next, then Ruiz or Povetkin if he beats Whyte. I doubt team Wilder will do business with Matchroom.
