Well, Dana's asked Silva to move up a weight class, and he agreed. It's on, Forrest Griffin and Anderson Silva at UFC 101. Obviously Griffin has to be the underdog, but I wouldn't count him out. His ground game is vastly underrated (Randy Couture even says he's one of the best he's sparred with), and his cardio is amazing. But Silva is one of the best in the world. We'll see; I'm pumped.
