Come Saturday, Nick Diaz will attempt to dethrone one of the most prolific fighters of all time.
It's been a work in progress to actually get him inside the Octagon with UFC welterweight champion Georges St-Pierre, but their feud outside of the cage has manifested itself in an uncontrollable blaze.
Diaz has more or less worked his way into GSP's head, making the champ more emotional entering a fight than ever before.
Taking that into consideration, it's understandable how hyped their showdown at UFC 158 is becoming.
Either St-Pierre's wrestling will stifle the challenger's elite boxing, or Diaz will put forth the recipe to end a six-year unbeaten streak in one of the UFC's deepest divisions, prompting GSP to make a move to middleweight and a run at Anderson Silva.
Here are Diaz's keys to victory as he finally gets his chance to prove he's the best in the world.
