With the upset of Anderson Silva still percolating through our minds I am left wondering who will be the next champion to fall and lose their status as the best fighter in their respective division. It is a very interesting time in the UFC right now because I believe that we are witnessing a period now in the organization where we they have a group of dominant champions in almost all the divisions. With that said I ask myself who will fall first and which one will be the biggest upset?Cain,Weidman and GSP appear to have the toughest fights ahead. Personally I am leaning towards Cain because in my opinion he is in the most danger of losing his title, but will it be the biggest upset since Silva losing his belt? Who do you think will the next fighter to fall to a man/woman not worthy of our respect ? Answer the poll and share your thoughts.
