Basically, for me atleast, you need to keep posture, you falling on the floor uke style you basically have lost, also the grab is your friend, as a good posture with a good grab will rip a player in two, and if your quite good you can do a move that if the enemy player is moving they make it worse, but anyway, if you go floppy, I really cannot help you, since I suck at going floppy and it just results me looking like a retarded person trying to jump.
