Manny Pacquiao has reached the point where he now suspects that Floyd Mayweather Jr. is not serious about ever fighting him. Pacquiao notes that Mayweather Jr. has been asking him to agree to an ever increasing amount of things before he’ll agree to fight him. It was originally drug testing, but now Mayweather wants him to leave his promoter Bob Arum before he’ll think about fighting him.
The thing is there’s no guarantee that Mayweather will actually fight Pacquiao even if he does leave Arum. That would put Pacquiao in a situation where he could wind up leaving Arum for no reason if Mayweather decides he still doesn’t want to fight him.
