For my money, NINE consecutive, CONVINCING UFC wins over Werdum, Struve, Crocop, Yvel, Gonzaga, Nelson, Carwin, Velasquez and now Frank Mir is one of the most impressive streaks in HW history. He's been nothing short of utterly dominant in every fight he's had in the UFC and to be honest, I think Dos Santos could not only become a record breaker, but the greatest HW EVER.
This is not hyperbole on my part. If he gets past Cain again and pulls wins over Overeem, the surging Cormier and maybe even the ultra improved Werdum, I think he'd be in Fedor territory as the GOAT HW.
Cigano's been a stud for the longest time without as much as a blip in his record since joining the UFC, the saying "the sky's the limit" comes to mind and unlike Jones or Anderson, I think Cigano has the advantage of being in the uber-cool HW "baddest man on the planet" division and has a likeable personna that resembles a happy, humble Terminator that gets over huge with fans.
Fedor had an awesome aura and I believe Cigano could seriously broach that level of invincibility within two years if not sooner.
