I wouldn't call him fat, he's just a bit soft like Luis Ortiz and Martin. Breazeale and Martin would be seen as fat in the 90's era but in this "Obesity Era" they are just a bit out of shape.
the fat boxer used to be a one off freak thing in each generation. Only in this one could you really propose to take a pick of several.
Gotta be the polish pastry chef Kownacki. I really do hope Deontay cancels the Fury fight, and gives this mighty ferocious warrior his well deserved title shot, lol.
If the names listed above were to have a round robin tournament I would back Miller at this moment. I think Gorman has the higher ceiling however, he's still learning but he's a skilled boxer with lots of assets and I think he may look more out of shape than he actually is.
