Most jukes or other fake-outs that'll leave you tackling nothing but air are done with feet and the upper-body movements. The hips don't lie. Watch the player's belt-bucklet to see which direction he's progressing and anticipate his movement. Maintain good breakdown position and keep your feet buzzing to be able to shift direction and catch up with his movements.

Stay wrapped. If you execute a good rip and your player doesn't go down or get taken off his feet, stay with him for as long as possible, wrapping up and holding on. If you slip down, that's ok, just keep holding on to his waist, legs, or feet to slow him down as much as possible and wait for the cavalry to arrive. Don't try to do anything fancy, just stay wrapped up and deadweight the other player to make it as difficult as possible to move.
