Slated to be the biggest fight of the year, Silva v. Sonnen II has all the trappings of a legendary fight: shit talking, long odds (Silva is currently a 3-to-1 favorite), and history. Anderson Silva, the undisputed Middleweight champion, is going up against a rambunctious challenger, Chael Sonnen, who had him on the ropes for most of their first fight before Silva submitted him in the closing minutes.

Silva, who is looking to extend his winning streak to 16 straight wins, has promised, "I'm going to make sure every one of his teeth are broken, his arms are broken, his legs are broken." Sonnen says he will back up his trash talking. In fact, he's looking forward to the "medium rare" steak that he wants Silva's wife to prepare for him after beating her husband's ass.

This is going to be an epic fight that will change the state of the UFC. In anticipation of the biggest fight of the year, here are 5 Things You Need to Know About Silva v. Sonnen II.
