From what I saw there is no way ODH won that fight. I'll give him credit, he fought a great fight and came in with a solid gameplan and he made it a lot closer than I thought it would be, but he lost.
Floyd took longer than usual to adapt to his opponents style and was far less impressive (or if not impressive, dominant) than he usually is, but in the end he clearly and convincingly, in my mind, won that fight.
Props to him, I wasn't sure he could at 154 and I thought Oscar might be able to hurt him or put him down, but he did it. Floyd landed more punches (57% connect rate with power punches) with a higher degree of accuracy. Oscar was the aggressor, but it often was not effective aggression.

Sorry for the rambling-ass post, I'm a bit drunk.
