Julio Cesar Chavez was also a huge PPV draw back in the early 90's as well for a lighter weight fighter.
e.g. His fight with Whitaker drew a 5% buy rate or around 1 million total PPV buys;
"The fight generated an approximate 5 percent buy-rate, with over 1 million subscribers purchasing the fight, according to Suzan Couch, senior marketing consultant for SET. "We were marketing for a 4.5 percent buy-rate so we were very pleased with the results," she said.
Operators' estimates, however, were slightly less; they tabbed the buy-rates at below 5 percent. They said between 950,000 and 1 million subscribers bought the fight. Nevertheless, the fight, with a gross of approximately $30 million, will likely be the highest performing non-heavyweight PPV boxing event ever. …"

Chavez fights vs the likes of Camacho and Haugen also drew tremendous buy rates for the time too;
"Showtime Event Television (SET) and KingVision expect to exceed last year's Chavez-Hector Camacho fight, which generated a 4.2 percent buy rate, or more than 800,000 purchases, said Suzan Couch, the senior marketing consultant to SET. But a lower 3.7 rate, or 740,000 buys, was figured by Paul Kagan Associates, a media research firm."

"King has to hope that buyers will view Chavez-Alli as the equivalent of the Chavez-Greg Haugen and Chavez-Hector Camacho fights, which drew buy rates of 3.7 and 4.0, respectively. Both buy rates are considered good for non-heavyweight fights but don't approach the best ever boxing buy rate of 8.4 for the Evander Holyfield-George Foreman fight."

What kind of numbers does he do if he had an available PPV audience of 100 million nowadays instead of the 20 million or so he had back in his day?
