On this week's episode of "Inside the Hexagon," we chat with the first-ever Strikeforce light heavyweight champion, Bobby Southworth! Known for his very memorable time on the very first season on The Ultimate Fighter, Southworth was part of a cast that included Forrest Griffin, Stephan Bonnar, Mike Swick, Diego Sanchez, Josh Koschek, Chris Leben, Kenny Florian, and others. The former champ delves into launching the BJJ program at American Kickboxing Academy, his ill-fated Strikeforce bout with James "The Sandman" Irvin (where the cage door flew open during the fight), his title win over Vernon "Tiger" White, his time on TUF, and more.
