I think the referee did a good job deducting points from Nathan; he just didn't react to the last infraction, the piledriver. I think it was because there were only a few seconds left in the fight. I feel that Nathan should have been disqualified; this is not the first time he has committed such an infraction. I remember back when he fought Cachorrao (Ricardo Almeida) for the Pancrase title; Cachorrao choked out Marquardt and he punched him several times after the stoppage. Renzo (Gracie) jumped through the rope and kicked him two or three times for the cowardly move.
