Will Dubois be a long time HW champion?

He could. He got hurt against Joyce & didn't want to end his career. He got robbed against Usyk.
Now if the ref and judges give him anything resembling an even shot he'll do just fine.

 

If he had a suspect chin he wouldn't have beaten Hrgovic let alone survived that bomb AJ landed on the 5th.

He beat the arguably 3rd best heavyweight in the world and former two time champion. He's earned the status as a champion, just not the top dog (Usyk).

 

A guy that got KOd by a jab from a Middleweight?

No way

His chin gets shattered again soon

 

He is not the Champion he was gifted the belt. Usyk is the real Champion. He does deserve a rematch with Usyk though.

 

The potential is there for Dubois to be a longtime champion.

He is only 27 and his timing could be just right with Usyk and Fury surely close to retirement and Joshua effectively done.

 

However long, he's going to be an exciting champion while it lasts.

 

Who knows. I think his defense is too leaky to be long term belt holder. But he is an exciting fighter and makes good fights.

His resume is shaping up nicely too. Good fight against Usyk in a losing effort, and now 3 straight wins over Miller, Hrgovic, and Joshua. That’s a solid run. Hopefully he gets back in the ring one more time against someone like Kabayel or Parker and then a fight with the Usyk vs Fury winner

 

One or two fights, unless he has Fury and Wilder like cherry picking abilities.

 

He seems to be willing to fight decent opposition so only a matter of time before he loses his belt. I have a lot more respect for someone who takes on the best opposition than someone who holds the belt hostage fighting weak opposition.
