You're right...
It was a very bad decision. Manny lead in all manner of punch statistic. He had Horn in serious trouble at the end of the 9th. Manny was never in trouble. He had a few cuts but they were from head butts. Horn had heart and was the aggressor for a great deal of the fight, but he was an ineffective aggressor. Most of the time he offered himself up as a punching bag while aggressing, and rarely landed much of anything when plowing in with his head lowered (the source of the head butts). You don't dethrone a reigning champ in a situation like that.

Manny Pacquiao losing is why boxing is such a joke. How can people take this sport seriously anymore? Jeff Horn did not win that, sorry.

That's the kind of thing that hurts boxing's reputation. Literally nobody except the judges in Australia had Jeff Horn winning.
