Dubois is far too stiff and upright to beat Hrgovic with the longer reach and who has a world class jab. Unless Hygovic is packing glass then I just can’t see any other outcome than Dubois getting stopped in the later rounds.
Dubois is a better boxer and has good power. Hrgovic... I've yet to see him against anyone decent. His best opponent was Molina. Atleast Dubois decent ok vs Joyce and was just beaten by a top level fighter.
Dubois is not much of a boxer or mover. He is a puncher who needs an opponent right in front of him. His critical weakness is his lack of head movement, predictability and stiff upper body. He is not difficult to find. For someone world level with a good jab and good movement who can box, its an easy nights work.
