Reason: It's old guard vs. new guard Although Rockhold is currently set to fight Lyoto Machida, in what itself is one of the most anticipated fights of 2015, Rockhold vs. Silva could actually be that much better. Rockhold is a former Strikeforce champion who, outside of Vitor Belfort, has been unstoppable since moving to the UFC. He's considered by many to be one of the bright spots in the future of the division. His game is complete - striking, submissions, he's the total package. Silva is considered the GOAT (Greatest of All Time) by many, but for the past two years, it seems like his time has passed. Seeing how he fares against and up and coming star - that would be exciting.
