Because Dubois got beat by Joyce through lack of head movement and had a padded, deceptive record just like Coffie, both figfhtes are too green at this stage except Dubois is far younger and has time to mprove.
Disclaimer: I am not a fan of Joyce at all. Joyce beat Dubois with one hand.............literally one hand. Dubois didn't lose because of a broken eye socket, he didn't even have the ability to force Joyce into second gear. Once it was shown Joyce was able to take Dubois' offense, it was pretty much over, let's not forget how Dubois was sucking wind in the corner............... Dubois attempted to force a pace he couldn't keep up, that was his real undoing, not the eye. Back to the original post: based on recent events, Dubois I believe would stop Coffie.
Daniel Dubois lost to one of the top heavyweights in the world. Michael Coffie just lost to.... Jonathan Rice. There's a slight difference. Dubois would knock the stuffing out of Coffee.
Dubois KO. Relatively easy, I think. On a sidenote, was so impressed with Jonathan Rice. Obviously has a ceiling and has many losses (against good opposition though), but his jabbing and counters were great.
