I have one question from a logic point of view. If Steven Segal is so bad and this is all a publicity stunt for him, then why do Silva and Lyoto carry him around? If they did not want him there, then he would not be there, there is no way he can force his way in to the videos or the weigh ins. So there are 2 possibilities.
One- Lyoto and Silva truly benefit from Segals teachings, mentally and physically so they want to keep him around.
Two- Segal, just like Vandamme, was a much larger celebrity in 3rd world countries ( not just Brazil there are many around), that Lyoto and Silva feel like they benefit from his presence in ways such as becoming more relevant and earning more American fans.
In the end truly a fighter is only as good as how many fans he has.
So which one?
