Shell Drill

The foundational team-defense shape: as the ball moves, defenders learn their assigned positioning — on the ball, in a help/deny gap, or fully weak-side help — and communicate constantly ('ball,' 'help,' 'I got ball'). Start slow, walking players through where to stand on each pass, then speed up the ball movement (including skip passes) so players react and rotate in real time rather than just holding a memorized spot.
