Entire Box is available. Any pass to the wing would "shrink the box."

When pass is made to wing, the box shrinks.

RULE: Once the ball is on the side, KEEP IT THERE!

X1 must jump to the pass and front a basket cut or DENY the pass to the swing spot

When ball is on the wing, on ball defender (X2) forces to baseline checkpoint and X1 prevents ball reversal.

KEEP THE BALL OFF THE SWING SPOT!

THIS PASS MADE THE BOX BIGGER!!

RULE: DENY ANY PASS THAT WOULD MAKE THE BOX BIGGER!

Pass to 3 would shrink the box.

Pass to 4 would increase the box.

Don't let 4 catch it on the swing spot!

X2 cannot allow the pass to 2 for this pass would increase the size of the box!
