Welcome to Sherdog. This is really ridiculous.
Before the yesterday fight, nobody could even acknowledge that Cain is much more well rounded than Brock or JDS and his ability to win came down to his gameplan, which was perfect this time.
Also, 10-12 fights which means only 3-4 top opponents (who ever have the same # of fights or over their prime) means that the fighters are not that experienced, and we have not seen them in all situations that can happen in a fight.
Overeem and Werdum are the only opponents who are truly experienced and still very dangerous. Ironically, except for the Werdum/JDS fight a while ago where Werdum clearly understimated JDS, we have not seen them fight any top UFC fighters.
