Brook will have a hell of a lot more viewers if he's fighting on the evening of a floyd fight, obviously. I'd prefer Brook vs Mayweather just to see entitled amir's reaction though khan is the more entertaining fight though it will only be competitive for 3 rounds, it'll have more action, Mayweather will beat Brook 10-2 in an admirable but boring fight.
Floyd v Rios would do better PPV numbers than Floyd v Brook. When did Brook become some big attraction that he would boost PPV? At the time he beat Porter? :rofl
Brook-Rios will be on HBO around afternoon and I doubt it's PPV. Floyd's fight will be later in the evening.
