Anderson Silva is the topic of nearly all superfight requests. His name is continually thrown out when naming potential opponents for Georges St. Pierre and Jon Jones. However, GSP has not been vocal about wanting that fight.
Nick Diaz thinks St-Pierre should be, and said if he were in St-Pierre's position that is the fight he would go after.
As recently as this past November, Cesar Gracie claimed Silva's camp was interested in this particular fight. Although, no official word has come from the Silva camp itself.
Diaz vs. Silva would surely get the MMA community interested. Diaz, a former Strikeforce welterweight champion, would not back down or run away from the top pound-for-pound fighter in the world, and the pre-fight antics might be worth the price of admission alone.
The fight currently looks unlikely, but should Diaz get past GSP, it could be on the horizon. If so, this is how the fight breaks down between two of the best in the business today.
