Other mistake: In the semi-final where John Lawrence fights against Darryl Vidal, the female referee has major problems of what to do. When Lawrence gets his first point, the referee first raises her red flag (Vidal is wearing the red ribbon) but then swiftly changes her mind. And when Lawrence gets his third point, the female referee again incorrectly raises her red flag.
Other mistake: The way the leader board is arranged its obvious the tournament is single elimination, you lose, you're out. During the montage, Bobby eliminates the same guy twice; you can tell its two different matches because the referees are not the same.
