From some of the quotes from Pacquiao he seems almost superstitious about having blood taken from his body so close to the fight. Almost like it would take something away from him. Floyd appears to be capitalising on this to gain a mental advantage and it's backfired slightly. Should Pacquiao act professionally and just take the tests? Maybe, but he won't. Should Floyd act professionally and not take the **** by ordering more drug tests than needed? Maybe but he wont. None of this means Pacquaio is a drug cheat though does it? Pacquiao's reasons for not agreeing to the tests Floyd wanted seem a bit silly but who is Floyd to go around insisting on it in the first place? Both fighters are to blame here. I still believe this fight will happen. It really IS too big not to. Perhaps with the help of someone like Goldenboy to broker a deal?
You also have to remember that Pacquiao was a 16 year old when he campaigned at Flyweight. It's completely natural for the human body to continue to grow up until early 20s. Pacquiao was just a skinny teenager back then- people forget that.
Its the refusal to do the tests that planted the seeds of doubt and the way he has made at least 3 different excuses as to why he wont do it. Which is it Manny?
