Yeah, I dont really know what people are talking about with Velasquez and a weak chin. Kongo was landing KO-powered punches but his ground game was so non-existant that it was embarrasing. He just didn't have enough time to finish and when he did, he decided to clinch which he should not have. However, Cain recovered every time so not only does he have a great chin, he also has great recovery ability. And Carwin hits harder than Kongo so if a potential fight against him goes the same way as the one against Kongo, Cain is going to get knocked the fuck out.
Also, yeah, Uno was raped. He certainly deserved to win that fight, no idea what the judges were thinking.
