The Leg Control Shot as demonstrated by Reilly Bodycomb is a quick way to land a Footlock from standing.
You are going to shoot in ( watch out for flying knees ! ) like you are going for a Single Leg but you are going to grab a Ball and Socket grip at his knee as you step both of your feet between his feet.
Once you're down there you will go underneath and wrap your outside leg for the Footlock as you slide your forearm from your opponents knee to his ankle. At this point you could easily change your grip and turn this into a Heelhook.
