Mechanically sweeps are very like throws. So your set ups have abit of cross over. Most of my sweeps are leg throws from a guard like position. The latch isnt 100% needed but secures the position. If you have them off balance you just need something to act as an axis to turn them over. If you can do the sweep single player. Look to find a setup for it that you can find in the multiplayer game. If you break the move into the setup, the motion and the finish find the defining features of each you'll start to see more oppotuities to hit the sweep or bail to another move. If someone blocks your sweep or somethng isnt right explore how you can bail to safety with a replant for example. Unless ive got a solid base i try to not force a move and flow into another one
