In MMA, there's an abundance of clichés. One of the most commonly used clichés is that "Anything can happen in MMA." UFC 156 truly lived up to that phrase.
First off, Tyrone Woodley scores a first round KO? Prior to his last fight against Marquardt, many fans considered him to be simply a boring wrestler who played it safe. Then he comes to the UFC, knocks out Hieron and literally declared war on the WW division.
After this, Lil Nog manages to beat Rashad Evans, by decision no less. While Rashad may not have had a sense of urgency to his game tonight, any way you cut it this has to be a big disappointment. Many thought that this was a squash match which only served to get Evans some momentum for a possible drop to MW or a fight against Anderson Silva. Pre-fight, Lil Nog's paths to victory seemed slim - either a flash KO or submission. If there was going to be a decision victory, it was supposed to be Rashad's. Now, Rashad has to go back to the drawing board and contemplate his future and MW possibly loses another viable contender. I guess Weidman can breath a little easier?
Which leads us to Overeem v. Silva. The only reason this matched was booked was to give Overeem a bit of buzz following his long suspension and to try and market a huge fight with either JDS or Cain. And it ended in a KO for Silva in the 3rd round of a fight that was likely going to go to Overeem. After all the talk on Overeem's end, he lost in a big way and now the UFC has to scramble to make sense of the HW division.
Somewhere, Dana White is screaming at the top of his lungs.
