i jus read you were trying to do hughes signature slam in ufc 2009? sometimes when you go for a takedown and your opponent defends it you end up in a double underhook position with you opponent sprawled on your back. when in this position press LB(i think it LB whatever the height modifier button is to do high kicks!) and rotate the grapple stick as if doing a major transition. your opponent can block it but just keep doing it and it shud work!
