The Next Big Thing?

To kick off season 5 of UFC NOW, we'll talk about a fighter who possesses all the elements to become the next big thing. We'll also discuss a champion who's on the cusp of making history. We are back with another edition of Roundhouse, where Michael Bisping and Kenny Florian will play a game of True or False? And you're not going to want to miss this week's Top 5, which is the Top 5 Devastating Knockouts.
