Its very strange, Ive seen fights get stopped when the guy on the bottom is not even getting hit flush but turtling not taking a single punishing blow, but the ref steps in right before the guy on top is going to gas out right when he sees him start to tire and his ground and pound or hammer fists start getting slow and weak and tired then he will jump in it baffles me, dont stop that shit, it slike they are protecting the guy who is gassing out so the one on the bottom doesn't come back and take advantage of wearing the guy out who blew his load from blocked ground and pound or hammer fists. Its not like they taking a Mark Munoz beating when he fought Chris Wiedman that fight should have been stopped he was taking so many clean flush power shots on the bottom yet the ref lets it go on long that was wrong. while some guys are shelled up not taking punches blocking everything with their arms and hands and the ref stops it. I always laugh whent he ref says defend or fight back, uh he is defending by blocking everything with his gloves forearms while covering up if he opens up the guy on top will hit him flush, let him shell up to let the guy tire out if he isnt hitting him clean on the face. In boxing they let you let a guy punch themselves out a boxer will cover up and deflect punches on the ropes then they unless a vicious combo when the guys hands get heavy and tired.
