Inbounds play from under our own basket
2 runs to the ball to get the inbound pass. 1 runs around him towards the three point line to receive the ball back. The 5 runs to the foul line to give a quick brush screen that barely makes contact with the 1's defender. The 5 then rolls to look for a wide open layup / alley oop and the 1 using the screen to get to the basket
The Key is for the ball to move quickly back to the PG and for him to use the center's screen quickly for an easy pick and roll. This is a designed out of bounds pick and roll.
Good team defence is five players guarding the ball, not five separate one-on-ones. The shell drill is where that starts, so here is how to teach help-side positioning and rotations from the first week of the season.
Rebounding is the least glamorous thing in basketball and one of the most decisive. It is also almost entirely a habit, which means it is entirely coachable.
Good spacing is only the start. The best modern offences teach players to attack the defence's rotations and play in a permanent 4-on-3 - here is how to coach that read.
