Fedor
I started watching mma early UFC. I was drawn to it because it determined out of several bad asses, who is the baddest. As mma progressed, I learned not all of the best were in UFC, however pretty much Pride/UFC had locked up the best of the best.
Enter Fedor. Nog was the clear #1, and then Fedor dominated him. There was no question, THIS was the guy, THIS WAS THE BADDEST OF THE BAD. This is why I started watching mma, to find who it is. It, is Fedor.
