“That only makes sense if he knew Manny would refuse the testing.”
That’s easy enough: Manny Pacquiao has said he won’t allow blood to be drawn within a week before the bout. So naturally that’s what Floyd demanded, since he is desperate to avoid the fight.
When did Manny say that? If it was before the issue of the drug-testing was raised for this fight then that would lead me to believe PBF is ducking. However, if that reasoning came up after the issue was raised then I'm still suspicious, especially in light of Arum's eye-popping and bizarre quote of "I've got a Filipino fighter who is superstitious" as a reason Manny wouldn't agree to it.
