Hughes was a wrestler, but when he got on top of his opponent he would pund the sh** out of him. He has the head for it. I don't see the agression in Kos like the young Matt Hughes had.
I honestly don't see Kos bieng an elite MMA fighter ever. Maybe a succsesful Div 1 Wrestling coach or something along those lines. Remember ALL the fighters are evolving quickly, alot at a faster rate then Koschek
