If someone gets elbowed 4-5 times and he isn't able to defend himself, the fight should be stopped. Saying he was about to defend the next elbow is a weak argument when he's already eaten 4-5 without blocking those. I wanted to see Ortiz beat on Ken some more, but it's too bad Ken's defense sucks.
And it's the same thing with the Tanner/Frankling fight. Except Tanner was already dazed when he went down and was getting beat by Franklin. Bent over with your hands placed on your head is not a good defense, it should be quite obvious he wasn't completely focused at that point. I have no idea why anyone would say Tanner/Franklin was a bad stop.
