Play the set and the spin with someone on your back: receive side-on, set it first time, and turn away from the pressure into the space for the next pass.
Put a marker at the foot of the Y with the line of players and two balls. Ten yards up from it, put a marker for B, who stands there with a defender tight behind him. Twelve yards on from B, place a pole on each arm, about sixteen yards apart, with one player behind each. A passes into B and steps out to support on the side of the arm the ball is going to. B sets it straight back first time, then spins away from the defender and runs up towards that arm. A plays it sharp into the arm player and goes in as the next defender. The old defender drops into B's spot. The arm player shuffles out from behind his pole, receives on its inside and lays it off first time to B, then spins round behind the pole. B plays it first time into his run on the outer side and follows to the arm. The arm player carries it home on a diagonal. The next rep goes to the other arm.
A pivot in a game almost never receives with time. Someone is on his back, and the pass into him is only useful if he can give it back first time and get away. Unopposed Y drills groove the pattern but not the feel of a body behind you.
This variation takes the pole away from B and puts a defender there instead. B receives side-on, so he can see A and feel the defender with his back and arm. He sets it straight back first time, keeping his body between the ball and the defender, then spins away from the defender's side and runs up towards the arm for the second wall pass.
The defender's job is light pressure. He follows B a step, so the spin has to be sharp, then drops into B's spot for the next rep. Full pressure is a progression, not the start: the aim is passing under pressure, not winning the ball.
The rotation adds the defender to the chain. A goes in as the next defender after his pass to the arm, the old defender becomes B, B follows his wall pass to the arm, and the arm player carries the ball home. Reps alternate arms, so B spins both ways.
Save it to your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block. Or start from a blank pitch and build your own.
