toughest competition in UFC history?

[Clark Rogers]

He should get more respect for what he did.

Absolutely.

I doubt you ever see another instance quite like it. The fact that he was able to come in and compete with the best there was without any fight experience is nuts.

People like to shit talk how he couldn't take a hit, but really... I dont see anyone going from no fight - particularly striking - background, to fighting Cain V 2 years later and taking a hit any better lol.

Mir and JDS.

In terms if skill faced throughout every fight, Brock

Sonnen also deserves a mention. He fought:
A. Silva
Jones
Fedor
Shogun
Tito
Evans
Bisping

 

[Madmartigains]

Arlovski.
