Easily. If treacle footed plodders can have Marciano swinging wildly and falling into the ropes like a Saturday night drunk, imagine how stupid Byrd could make him look.
Hell I'd even back Roy Jones to make Marciano look like a disabled person as long as he didn't get his chin touched.
survive? lol byrd wins by decision, southpaw, faster ,stronger and bigger,wider than charles, marciano was easy to outbox like hell and very short and probably the slowest guy that fought byrd
