I can't see Floyd KOing Oscar for the life of me.. DLH has never been remotely chinny and has fought much bigger punchers than Floyd. Thing is, Floyd does have enough power to stun Oscar, but in order to actually put him in any trouble he'd have to follow up with numerous shots. And in doing so, since he doesn't throw or generate power in combinations, give Oscar time and space to punch back. Floyd does not want to get in any exchanges with DLH, it's just stupid on his part. If there is a KO between these two guys, Oscar will be the one standing. He probably has enough power to put Floyd to sleep with one hook, and Floyd has to prepare for the fight with that in mind, always being aware of it. I got the impression from their first matchup that Floyd was actually at the most risk when he was landing his best punches, such as in the 5th when Oscar managed to back him up against the ropes. Floyd had to respond with some hard shots, and he did, but that's not a situation he want's to be in against Oscar. I'm pretty sure Floyd already hit DLH with his best punches in the first fight, he knows he can't KO him, but I suspect he will also have Oscar's respect in the power department, which possibly wasn't the case going into the first fight.
