Yeah I messed it up. I still come up with a draw, 115-115. I fixed the original post. I will go back and rewatch the even rounds so I can get a more decisive decision.
I went ahead and looked at it. The first half of that round is won by floyd by a small margin, then the 2nd half Castillo just outfought him. Yes Floyd did block some of those bodyshots but not enough. Based on how many headshots floyd landed against castillo's bodyblows and Castillo's agression plus the fact that it was the 12th round, seeing that castillo was more agressive I would have to give the round to Castillo still.
