How do you get the thrower back into the next action?

Make the thrower part of the next action. In a 4v4 or 5v5 game, restart every ball with a throw-in and temporarily award an extra point if the thrower receives again within the next two actions. That condition should not stay for the whole session. It simply exaggerates the idea that the thrower can step back onto the pitch and create another support angle. The receiver also learns not to treat the first pass as the end of the restart. Ask the thrower: where can you move so the receiver can see you without bringing another defender into the same space? Sometimes the best movement is behind the ball, sometimes inside and sometimes beyond. The aim is not a fixed give-and-go. It is helping the thrower recognise that their involvement continues immediately after release. To keep the choice open, you can reward the thrower simply for becoming a visible option again rather than for actually receiving the next pass. The coach observes whether the support angle reappears, then removes the condition after a short block to see whether the habit remains.
