The goal of this offence is to counter a 2-3 zone defence.
To do that we need to create a triangle on the wing.
For this offense to work, you need to force the low defender of the zone to guard the basketball on the wing. This is the reason why the players on the wing start closer to the corner.
This will allow you to split the middle defender with your two post players which is a very advantageous position for the offensive team to be in.
Four players standing still make every ball handler's job harder. Teach V-cuts, L-cuts and back cuts so your team gets open and punishes defenders who overplay.
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.
