Dubois in just three rounds. Charr hasn't been a top heavyweight since at least 2017 and probably even before 2015 I would say. Big destruction of Dubois if the fight takes place. I would be the German, I would box Trevor Bryan and even then it's not certain that he will win.
Dubois KO inside 1 or 2 rounds and the lad deserves an easy one after facing stiffer opposition recently than most.
I think he was a "solid" fighter in his prime. Good enough to beat your average -to -good boxer but failing when stepping it up to the highest levels.
My honest prediction of the odds for Dubois V Charr if im being generous. Dubois to win 1/50 Charr 35/1 That is how close the fight is.
