....everytime a fighter rules in a division or has a good undefeated streak, his future opponents (=all the other guys in the division) study him like crazy. They study every move that he makes and train to develop a style which can be effective against the champion's weapons. There were already AT LEAST 2 examples in UFC history: 1.) Brock Lesnar: when he came to the UFC nobody could stop his takedowns. He was a monster coming at you at highspeed to take you to the ground and pound on you once he had you off your feet. So later everybody did nothing but takedown defence training and suddenly Brock couldn't take them or keep them down anymore: examples: Cain Velasquez. And against Overeem Brock Lesnar didn't even try to take him down anymore cause he knew it wouldn't work 2nd example: Lyoto Machida: for those who forgot, there was a point where he looked invincible and was the undisputed king of his division and his opponents weren't even able to win a single round against him. That changed quickly later after his opponents studied his style and trained all day long to be effective against his style. Same with Dos Santos: he WAS so good. And no, he was not overrated and no, he didn't get exposed. Cause JDS did beat all those really good fighters in the UFC. He wouldn't have beaten those guys so "easily" if he wasn't THAT GOOD. But Cain and probably the whole division focus on JDS' style so much and try to develop a style that can be a solution to the "problem" named Junior Dos Santos. And finally it worked. Has nothing to do with JDS having been "overrated". UFC history has shown that nobody is dominant for more than 2 or 3 fights at the top level. Only exception would be Anderson Silva and GSP.
