Query: Escapes didn't work in judo

Great introduction to basic BJJ. The section for escapes are literally impossible to pull off (at least in my judo practice) when the opponent is really trying (his partner's loose mounts on him in the video is almost laughable). I've never done any BJJ in real life but I have done judo for 3 years and nobody in newaza sessions would mount me so loosely as demonstrated in the video. Never the less it's still a great introduction DVD to BJJ.
