Forrest Griffin's Jiu-Jitsu instructor Robert Drysdale was asked by the UFC Countdown Crew on his opinion of the bout between his student, Forrest Griffin, and Anderson Silva. Drysdale stated Forrest Griffin would most likely submit Anderson Silva, based on his expert opinion. When the UFC Countdown Crew visited Anderson Silva, he was quick to lash out and question Drysdale's opinion. Anderson Silva even went as far as to directly insult Drysdale and call him an idiot.
Interesting, Drysdale seems like a good guy, and obviously has the grappling credentials to give an opinion on things.
