Spring the offside trap as a unit. Hold a flat line, read the striker's run, and step up together on the trigger so the pass finds him offside. One caller, one movement, everyone level.
Set a flat back four against two strikers and a server. As a striker makes an early run in behind, the line steps up together on the caller's trigger to leave him offside when the ball is played. Emphasise one voice, a flat line, and stepping as one so no defender plays the runner on. Vary the timing of the run and the pass. Rotate the caller and the roles.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
