As many have stated, K1 has little relevance to MMA. Reem was sweating the take down so hard, he was unable to execute his striking game. Which was mostly unwarranted in retrospect, because he showed good defensive BJJ when he had to. He was based out good, and hard to sweep from the top, and demonstrated the ability to escape and stand up from the bottom. I think he could have postured up and GnP'd from guard, effectively.
Also, what really surprised and disappointed me, was the bad cardio both displayed. I could not see either going 5 rounds in a championship fight right now.
Jorge looked peaked, very impressive. I surmise he will get wrestle fucked by Gilbert though. He did something many fighters fail to do, as well. And that is, exploit a boxer's bobbing, weaving, and front heavy stance, by using well timed knees and kicks.
