I don't think it was the judges personally, I think money decided this fight. Bob Arum (being the money grubbing pig that he is) was just upset that his cash cow in Manny had just been deflated - he needed an excuse as to why Manny looked so terrible in the ring, and the first thing that came to his head: "damn Mexicans." Little did he know that the entire world had just seen the fight on primetime and any half-brained boxing fan can see that Marquez won by a comfortable margin.
For me, this is the straw that'll break the camel's back. I think I'll have to go back to only watching amateur boxing or find another sport. Between the NBA lockout and boxing going down the toilet, I really think I'm going to need a hobby because I'm done with this shit.
