Ruddock of course would have a punchers chance. But I think Bryd wins a decision. Ruddock wasn't a pressure fighter like Ibeabuchi he was more of a slugger like Tua who Byrd outpointed. Ruddock never had a great work rate or applied much pressure he waited, jabbed (in his prime) and looked to land the smash. Byrd's too elusive and smart to get caught against such a predictable opponent.
Byrds just asking to get Ko'ed ala Ibeabuchi. He doesnt have the power to hold off Ruddock or put Ruddock away quickly like Lewis did.
