Who wins? I haven't seen much of Darius but he seemed to be the busier fighter than Adamek, and fought with more energy, whereas Adamek is more of a sharp shooter. I think this would've been a great fight - maybe not unlike Adamek's second fight with Briggs (didn't see their first one). Whatever happened to Briggs anyways? Is he still fighting?
I'd take DM. DM was about 2 light years better than Briggs, who twice gave Adamek hell. I think DM's jab, and pressure would be too much for Adamek.
