One is covered with tattos and said he was afraid of needles when they asked him to take the drug test. The other said let's take some test as soon as suspicions came up. That says alot. If you aint dirty you got no problem testing. If you might be dirty you are suddenly offended by the accusation and suddenly become afraid of needles.
In the 24/7 episode I saw Marquez working on putting mustard on his shots, but I wouldnt gawk at his speed. He was throwing power shots at a punching bag, alot of them wide hooks. Marquez is not foolish to throw those types of wide hooks at Pacquiao unless Pacquiao walks into a straight shot and gets hurt first. The same thing goes for Pacquiao. He's not going to put everything he has into his shots because he simply respects Marquez punching power and know from experience Marquez can hurt him.
I wonder why Pacquiao was holding back and throwing so many arm punches in fight 3. It could'nt be because he fears Marquez feather fists! :think
