Anderson Silva defeated the biggest challenger to his UFC title in his illustrious career after dropping Chael Sonnen in the second round at UFC 148 on Sunday at MGM Grand Garden Arena. The UFC middleweight champion survived being dominated by Sonnen and overcame great adversity.
At age 37, Silva is entering the twilight years of his career yet is still performing at an elite level. Yet the pound-for-pound best fighter in the world is left without a clear direction in his career at this point. His biggest rival has been effectively removed from the title picture and very few fighters seem to have the skills to dethrone the champion.
With Silva seemingly becoming more and more unbeatable with each title defense, fans have to be wondering if "The Spider" will keep the UFC middleweight belt until he retires?
Silva still has a few years of fighting time remaining in his body and has yet to slow down inside the Octagon. A string of new challengers will be competing over the course of 2012 to secure a title shot and hope to end Silva's reign of dominance.
Do they have what it takes or will Silva remain the UFC champion until he leaves the Octagon forever?
