This is a tough fight to call to be honest. Mercer was good but he was a tad overrated, and Dubois has probably got a better wins than Mercer lets face it.
I still dunno about Dubious' chin. If I could be confident of his chin then I would take him over Mercer without thinking too much. DD is much bigger, hits harder and is probably even a better boxer.
I've gone for Debois KO. He dwalfs Mercer and he's relentless. Mercer was lazy, lost to Ferguson and ancient Holmes way past his prime. He gets overrated over Lennox and Holyfield boxing down to his level. He's not been knocked out. He got his orbital bone broken and he quit twice when overwhelmed by the best HW boxer of the last 20 years Mercer isn't even a puncher either. He couldn't put away granpa Witherspoon or Ferguson in 2 attempts who Bowe sparked in a round. I fancy Debois to have a better chin than Morrison.
