LAS VEGAS — Floyd Mayweather, preparing for his May 3 fight against Marcos Maidana, was humorously diplomatic this week when asked about promoter Bob Arum’s latest gambit to force a superfight between Mayweather and Manny Pacquiao.

Arum suggested this month that boxing fans should boycott the Mayweather-Maidana fight, suggesting they not buy tickets to see it live at the MGM Grand or watch it on Showtime pay-per-view.
