I don't know why Kongo took this fight - very foolish. First of all his ground game sucks and if the fight goes to the ground Roy is going to simply dominate. Second, Kongo gets knocked out easily if he doesn't dominate. On the other hand Roy can take INSANE punishment. So looks like a terrible match up standing up too.
Basically, Kongo's going to get knocked out. This fight is very easy to predict.
