Great performance by Cain. I think there are some aspects of the fight that must be noticed:
1. Cigano training was not the best possible. He gave too much emphasis on strength training, and the result was no guard and a demolished face in the end of the fight. Besides that, I think he should have trained with some good quality wrestlers in order to prepare for Cain's takedowns.
2. Despite being better on striking than Cigano (which I was not expecting), Cain had some weaknesses on his striking game, putting his head down TOO much times and he could have been KO'd by JDS with an uppercut or a knee at any moment. Apart from that, he dominated Cigano the whole fight and deserved the belt!
