It seems that the same rule of judo applies to wrestling as well. If you don't get a good grip you won't throw( unless it's a leg attack). I probably wouldn't have as much of a problem throwing my judo colleagues if they didn't wear a gi. But somebody who knows how to impose a good grip without a gi can shutdown most of my game.
