I don't see anything dirty about 1 & 2 in context to the early UFC's as these were all legal. Elbows to the face and wrist holds are still legal. 3, is just bringing in a weapon. I would think that in KF tourneys, they would check for it. I guess this little guy trains KF. Early UFC's basically had zero disqualifying rules, which pretty much dispelled and answered all myths about that "street fight to the death" boogeyman.
