This is just Seagal trying to keep his name in the MMA media. What possible reason would Couture have to accept a "no witnesses" fight? That stipulation was made to ensure that the fight didn't happen. Seagal has no interest in fighting for real. As for Seagal outshooting Couture, I wouldn't bet on it. Couture is a shooter too and Seagal never impressed me much. It annoys me that Silva and Machida keep this bozo around.
As I go through life I keep coming to the same conclusion, people are generally stupid.
