Anderson Silva will face Forrest Griffin at UFC 101, a fight that has gotten many fans talking immediately. This co-main event already looks to be overshadowing the lightweight title fight between Penn and Florian. Win or lose, what happens next for the Spider? If Griffin breaks his UFC win streak, he will most likely go back to defending his middle weight title. However, if he wins will he stick around the light-heavyweight picture a little longer? Will he keep jumping back and forth between the two weight classes, or will he vacate his middleweight title in pursuit of light-heavyweight gold? Regardless of which route Anderson Silva takes, there are many opponents waiting for their shot at the pound for pound king. First let's talk about potential middleweight title contenders, then we'll move onto the light-heavyweights.
