If you watch HBO's Cotto Greatest Hits, this wasn't the first time that Cotto was in serious trouble in a fight. Corley, Judah, and Ramirez all have stunned Cotto at 140lbs. No one ever questioned Antonio's chin before the fight.
Cotto has been fighting smaller 147lb fighters that started their career at about 135 lbs. Margarito "The punching machine" was the first full-sized 140lb fighter he's fought. He was exposed, just a little too small to fight these bigger guys.
Cotto should fight Cintron, who would help to prepare him for a Margarito re-match in 2 years.
If Mosley, who was busted for PEDs can agree to a blood test, why can't Pac. I don't believe his religous b.s. or that drawing blood will weaken him.
Plasma volume usually returns to normal levels within 24 hours after DONATING blood where they take 450 mililiters or a pint of blood. We are talking about a drug test where the syringe itself cannot draw more than 10ml. Doing the math, it will take the body about 30 min. to recover that amount of blood.
