Golden Boy is stepping on their own shoes. Loma's name is bigger than Ali's and Linares is their fighter, why compete?
I doubt this event was about making an real money. It was just to make some. And HBO dates are hard to come by. I doubt they will loose money. And HBO wont loose money if the ratings are bad. They have a set budget and if the ratings are bad, they might decrease the budget, but they wont take a loss. GBP has HBO and ESPN2. Thats not a lot to work with. So they have to make the best they can.
Loma vs Linares was too big of a fight to pass up, and Linares pushed hard for it. So they kinda had to do it. And due to time zones, i dont think they will compete at all. Loma/Linares in New York and Ali/TBA is in California.
