I can't see Manny being able to cover the distance without getting jabbed. He has head movement but only when he slows his footspeed. He doesn't have prime Tyson style head movement where he can move his head while coming in at full speed. Manny uses it to get into range and feint before throwing but Floyd will just step back. Eventually Manny will start lunging. I don't see Manny getting knocked down by a left hook early like Marquez did becuase he keeps his right hand up high during the early rounds but just like Marquez he will eventually go to parry a left jab that doesn't come and get hit with the left hook. The only other advantage Manny has is that the left hook is a punch he's been training to avoid in his last two and next fight but Floyd's isn't a liver shot and is the fastest and most accurate he's ever faced. But I think if Manny can somehow get close enough, often enough, flurry enough and can get out he has a chance. He has the combination handspeed, stamina and style but I don't think the ability to get into and stay in range. Plus he isn't a dirty fighter and won't hit Floyd low, his hips or kidneys.
