no such thing as luck in striking in mma or boxing imo,if a person is trying to hit a target whether its with nice technique or lousy technique,and they hit the target,chin,body,legkicks ect,then its not luck.it would be luck if for instance a guy was trying to throw a nice thai kick to another guys leg and the opponant just happens and try,s to shoot in for a double at the exact same time,and the guy who,s kicking catches the opponant on the head and ko,s him even though he was intending to hit the guys leg,that would be luck.if you watch the chuck vs babalu 1,chuck throws a combo and then comes with a legkick to babalus body to finish up the combo,babalu thinks the kicks coming for his head and makes a basic error and ducks into the bodykick and gets nailed right in the chin by chucks intended body kick and hes ko,d.thats luck on chucks part,chuck wouldve most likely beaten him anyway but it just came quicker.bas rutten is an expert at mma/streetfighting and says the same
