Who's buying these numbers?

Half-witted predictions of as many as 3 million buys for the May 1 Floyd Mayweather-Sugar Shane Mosley bout can cut that in half. Or more.

HBO says there were 1.4 mil buys (740,000 on cable, 660,000 on dishes), bringing in $78.3 million, which makes it the second-best grossing non-heavyweight PPV fight in boxing history. The most: Mayweather-Oscar de la Hoya, which did $137 million and a record 2.4 million sales in '07. The previous second-best was De La Hoya-Felix Trinidad in 1999 ($70.6 mil).
