it was the GNP that actually KOd Velasquez, a good shot behind the ear. Happened to randy, gsp,etc...
The point is that to assume that Dos Santos wouldn't be capable of defeating Cain again is more than just a little farfetched...
Besides the fact that he beat Cain before, you also have to consider that while he lost their recent match (Cain certainly deserved the win and dominated in all 5 rounds), Dos Santos survived all the way to the judges decision and took a beating like very few can.
That said, if Dos Santos were to bring his best striking game to a rematch and apply serious takedown defense (one of the things he is known for), you can very easily have Dos Santos taking his belt back.
