where i am from you stand facing each other and swing like **** untill someone gets knocked out then you kick they head and ribs and head again untill the police drag you off very rear do fights last long enough that grappling skills can be used as if you are both on the floor then it is a free for all with everyone watching who will throw the kicks in.
Read again it doesnt say a boxer and his mates vs an mma fighter. Also round where you are in the back end of Wales how many good grapplers do you know?
