I don't think Dubois can take a punch. If he is over agressive he might get countered and get knocked out. Trevor Bryan has decent power and he has sparred top guys for years. Don't get me wrong. I think Dubois wins probably in midrounds stoppage, but Trevor will be dangerous and can cause upset if Dubois is careless. Especially if the fight goes to later rounds I'm not sure Dubois knows what to do if his punches have no effect. Trevor might stop Dubois in rounds 9-10.
Dubois is overrated. Bryan probably underrated. I don't rate Bryan but i don't rate Dubois either. I expect Dubois to win this but i doubt it'll be a blowout in the early rounds.
I'm going with Dubois via mid round TKO/KO. That said, Bryan is still a live dog and has a puncher's chance at the very least. Not sure where Dubois career will go if he takes the L. Doubt this one makes it 12 rounds.
Only danger Bryan poses is if his fat ass falls on top of Dubois when going down from being KO'ed. I don't even rate Dubois as I picked Joyce to beat him but Bryan is truly awful.
The only time Trevor Bryan looked like being a serious prospect was when he beat Derric Rossy (the same guy who gave Glazkov, Eddie Chambers, and Stiverne big problems when they were in their prime) by a wide decision. Unfortunately, that was back in 2015. Nothing positive to report on him since then as far as I can see. Actually, he's regressed. First time he takes a real flush shot from DD, I think he's going to crumple up like Martin did vs. Joshua. He gets TKO'd within 3 rounds.
