A year later, after both fighters have ‘retired’ to pursue other interests, could Mayweather and Pacquiao possibly do it all again?

They met a year ago this week in a fight that was the richest ever, even if it disappointed most of the millions who watched it.

Now there are rumblings, however slight, that Floyd Mayweather Jnr and Manny Pacquiao might be persuaded to do it again.

“I would say there is a possibility a rematch happens, yes,” promoter Bob Arum said Monday. “How big a possibility that is, I can’t really measure.”

Mayweather helped stir speculation over the weekend by saying in a Showtime interview that he might be persuaded to come out of retirement if the money was big enough. He said he had talked to Showtime and CBS about another fight and that “some crazy numbers have been thrown my way.”

Though Mayweather wasn’t asked specifically about Pacquiao, the Filipino might be the only opponent who can help him reach those numbers.

“If I came back, of course, it would have to be a nine-figure payday and probably a championship fight and a nine-figure payday,” Mayweather said.

Showtime executive vice president Stephen Espinoza said he is among the minority in boxing who believe Mayweather won’t come back. But Espinoza said he also believes a second fight between Mayweather and Pacquiao would do well.
