Why did Juan Manuel Marquez boast that he will take any test and than back out?

[Check_hooks]

JMM knows that there is public demand for him to be tested after the Pacquiao fight

People were in a uproar and petitions were signed

He still doesn't want to take the test because he knows hes dirty and it will take away that "feeling" like Arod has from hitting home runs

He agreed to the testing that was in the contract, then Bradley said he wanted Marquez to be tested by another agency on top of the one he had already agreed to. Marquez said "ive already agreed to testing im not giving into every demand you make" and then....this thread was made along with every other thread that Pacquiao fans have made to excuse Pacquiao's KO loss by implying that Marquez was juicing.
