I wonder if Sr. doubts of pacquaio's legit strength is the reason why they want a blood test. He should question how his son has a 40-0 winning streak....but of course rumor has it that they were mostly lower in weight than him. Plus, I havn't seen all of his fights, but the only one I have seen was vs. marquez, and his style is more of a hit and run rather than actually fighting. I guess by not moving around for him helps him keep his stamina, although I feel it's a cheesy way to win. I like fights like this one:
Manny Pacquiao vs. Oscar Larios - Full Fight Video keeps you on the edge of your seat. Both fought extremely well IMO.
