Kongo won hands down. He pushed the pace and dictated the stand up game against what looked like a timid unfocused Mirko. Mirko brought that upon himself, he should have been more aggresive and I think he should have wrestled Kongo on the ground. This lose will put Mirko at 9 or 10 in rankings, not sure if it will knock him off the list completly.
I would have been more impressed with Kongo had he KO'd Mirko. I've seen Kongo fight, and I like him as a fighter as compared to Gonzaga who I don't like.
