All the casual/celebrities and maybe some PacFan's was disappointed in Pacquiao's performance.
Pacquiao's stock has taken a big hit that's why they had Max Kellerman try to repair some of the damage on live air, literally BEGGING
Part of Pacquiao PPV Success which gelled well with American Fanbase was that he was a Direct rival to Floyd. Arum built Pacquiao's career Marketing/Mediating to everyone's belief "He is the one to beat Mayweather".
Now he has lost in unanimous fashion, we can agree, even on this site alone. Majority of everyone's belief is that he can't beat Mayweather. That's a big hit Arums Marketing Plan.
How will he market him now? ...
Arum's Agenda of injury, weather its real or not help's re-market Pacquiao for more fights not involving Mayweather. As he will try to build up Pacquiao again with wins over Algeri/Vargas caliber opponents. To bring back the belief again that "He is the one to beat Mayweather".
I personally think this time, the Media, Boxfans, and casual/public opinion wont fall for it. Along with the Shoulder fiasco Pacquiao has gained some Hater's.
Pacquiao would have to fight a risky fight next with some one new. Realistically possibly on the table is " Brook, Provod or Matthysse " otherwise I don't see it as doing over 400k buys at PPV.
He will always have his huge following no matter what. But that's clearly not enough for HBO as his lasts PPV Numbers with Algeri/Bradley II was real low. Imagine what his next one will be after this huge disappointment.
HBO clearly probably deciding to make Cinnamon-Boy as their New Number 1, Mexico is behind him with full force after Chavez Flop.
