I don't know how anyone could have watched that fight and called it anything but a win for Manny. Horn held, pushed, pulled, head locked, head butted... and yes, he was the one coming forward for the entire fight.
Manny landed more blows, landed more power shots, and damn near knocked him out in the 9th round. I wouldn't have called it a landslide, for sure, but Manny did enough to win. Boxing judging is subjective, and the judges saw the fight for Horn... but when every boxing pundit is saying that decision was BS... it was BS.
