the only reason Diego is undefeated is because he gets easy fights. the two hardest fights he had were karo and joe riggs. karo won that fight and ggot cheat by the decision and the win over Riggs was a fluke.koscheck is the read deal he will beat him this time.
diego won against karo by a split decision and karo did win that fight but got cheated by the judges. and if he dominated riggs way was there so serious moves till deigo got a lucky punch and riggs fell on his knees. he got lucky and thats it
