Payout Perspective:
Based on the ratings of the prelims and the ancillary telecasts, I may have underestimated how this PPV does. Over 1 million viewers on a night where boxing and basketball were on network television is very good considering the competition.
great night for combat sports all around, between the prelims and boxing, looks like over 4m people were watching fighting sports
Correction, well over 6m. Combat Sports OWNED Saturday night.
