I think Hearns wins by late TKO like he did with Andries. And remember Andries beat Czyz, as did Hill, two guys Hearns beat. I think Czyz is strong but his defense was not good and I think Hearns busts him up and stops him by swelling late.
I'm talking about the Hearns that lost to Barkley at 175lbs and the Hearns that had a knockdown drag out war with Freddy Delgado at cruiserweight who previously was stopped early by Prince Charles Williams and Michael Moore. At that time Showtime was setting up a fight between Hearns and Czyz, Then Hearns struggled so much with Delgado that the fight never came off. I assume that was the reason but I'm not sure. Who do you think would have won at that point? Did you see that fight? Hearns was pretty much shot but it was a hell of a war.
At 175 Hearns by late KO or decision. He'd control the short armed Czyz from the outside and keep him honest with right hands.
