Anderson Silva has the most riding on this fight. This fight will be a telltale sign on the future of his career. How well does he come back from his devastating leg injury and how is he now that he's a bit older. Losing to a man in a lower weight class will not be good. Although with a win or loss I have no fear that Anderson wouldn't get another top opponent even if he's brutally finished. Nick Diaz has everything to gain. Win or lose he's going up a weight class and fighting a legend. Whether or not that legend is on the decline does not matter. Anderson is still one of the best. So what are Diaz and Anderson's next fight if they lose? I think it's ridiculous that Anderson gets a 2nd shot at reclaiming his belt from Weidman on a win over Diaz, a WW, but whatever, this is the UFC. What does Diaz get with a win over Anderson? (Obviously not a MW title shot at Weidman).
