Georges St. Pierre vs. Anderson Silva would most certainly pair up the top two pound-for-pound fighters in the sport, barring another big win by Cain Velasquez, or a surprise by Jake Shields.
Since our site only started about 3 years ago, I created a procedure which acts as a good approximation of our Top 10 division dominance list, back to the beginning of MMA history.
Only once before would our #1 have faced our #2, and that match ended by no contest (Fedor Emelianenko vs. Antonio Rodrigo Nogueira II). Let’s not hope for a repeat! For the record, Wanderlei Silva inched ahead of these two, and took #1 on the list prior to their 3rd matchup, only to be beaten shortly after by Mark Hunt.
Furthermore, its also important (and amazing) to mention that Georges St. Pierre has never fought above the Welterweight limit, not even pre-UFC, which makes the proposed battle even more tremendous.
