Best representative for MMA right now? I think he is.
Bull. dos Santos is a good guy and all but there are plenty of other athletes in the UFC that are better representatives for MMA than he is.
There's no way JDS was "reading Cain like a book". He threw a punch and it landed on the right spot. Not discrediting dos Santos' win as it's hard to discredit a knockout, but he got a good punch in and Cain went down. Hopefully Cain will avoid dos Santos' power strikes this time around and get a TKO on the floor.
