Pride, UFC and K-1 MMA Statistical Ratings, Sep/2006
This is my attempt at objective fighter performance ratings. Only fights in Pride/UFC/K-1 mma were used in calculating these ratings. I didn't list fighters that were in the negative (1600ish or below) to save time.
I know these wont be that similar to a lot of peoples top 10 lists, but it isn't supposed to be. It only looks at who beat who and thier ratings... not how easy/lucky they won (subjective) or who would beat who or who is better/more skilled (also subjective).
