Mu Bae Choi vs. Marcio Cruz: Dog Fight for MMA

I thought this was an interesting way to apply "The Dog Fight" for MMA. At 3:23 on the video, Cruz uses his double under hooks to get up to the "Dog Fight". Choi puts in a whizzer to keep Cruz from taking the back. Cruz secures his position, and begins to punch Choi, who is wide open. After Choi has had enough punishment, he lets go of the whizzer. At this point there is nothing stopping Cruz from taking Choi's back and he does so. This proves to be the beginning of the end for Choi, who eventually, after a great deal of punishment, taps to a triangle/armbar.
