NO the last thing we need is another stupid weight class.:dealkovalev just won the belts at lhw let him have an actual title reign before he moves up for fuk's sake.
Its possible but improbable. Maybe if he cleared out 175 and had no other challengers there he could step into Cruiser and from there the temptation is always there to go all the way to hw if a weak, not too big titlist was around.
If Wilder(somehow wins) vs Kovalev would be PPV I'd favour Kovalev in that fight just for his boxing knowledge. Like that Counter he hit Hopkins with, if he hit that on Wilder, Wilder's not getting back up.
He's not young, so its not like he has any filling out to do. I suppose he could do okay against some smaller heavyweights. His style is reliant on him being the stronger guy though, that wont work against really big guys. A good example might be Jirov...though Jirov was more busy with his hands.
