UFC fight last night??!!?? and What you think?

Liddel vs. Silva. I was really disappointed that Silva did not win. It was like watching another Silva that night. True that it was an awesome fight but I've seen Silva much, much better than that. The knee strikes was not there, the "ferociousness" was not there. There may be "reasons" that Silva was not able to showcase his true self that night. When Chuck went down, why did Silva not pursue him to the ground? In his Pride fights, he always pursues his opponent and pound him. It may be because the cage is much bigger than the ring, it may be because he's training in the US is very much less different than when he was still in Chute Boxe but whatever the reasons his style that night was just slugging it out. Jui jutsu was not there, Muay Thai was not there (a few weak kicks, no knees). It was like he's not using everything in his arsenal. Did he wanted to LOSE?
