Both Anderson Silva and Stephan Bonnar entered the UFC with a bang. But since then, both of their careers have went down totally different paths.
Silva became the king of the middleweight division after wrecking Chris Leben in his UFC debut. He's yet to taste defeat in the Octagon and hasn't been challenged outside of his two fights with Chael Sonnen.
"The Spider" has grown so bored of defending his belt at times that he's stepped up a weight class. Despite fighting at a weight class 20 pounds heavier, Silva didn't miss a beat.
He'll jump up a weight class to meet Bonnar, who has made a career off his exciting fight with Forrest Griffin on the finale of The Ultimate Fighter season one. Since then, Bonnar has had an up and down career and appeared to be on the chopping block but has since won three-straight bouts.
Although the two men have taken separate paths to get to this point, both have had a moment in their MMA careers that has defined them forever.
