Automatic "Base Go I"
When the ball reaches the area of the free throw line extended, the defender on the ball pushes the offensive player toward the corner or to the baseline checkpoint. If the offensive player penetrates on the dribble inside the base checkpoint, an automatic trap takes place with the low "Helpdside I" defender quickly stepping out to "Lock Up" on a baseline trap. Other three defenders rotate into a Triangle I with all of the SOS "near man" defensive rules in effect.

Phase 1. Baseline Trap.
Defensive player X3 pushes wing O3 to base checkpoint. When O3 penetrates on dribble inside the base checkpoint, the nearest defender, X4 steps out and traps O3, with X3. X5 rotates over and assumes a pass denial or post front position against O5. X2 drops to low Helpside "I" position against O4 and X1 assumes a high Helpside "I" position ready to closeout on O1 or O2. All players rotate simultaneously.
Note: No trap will occur, if offensive player does not penetrate inside the baseline checkpoint.

Phase 2. Pass Out of Trap When O3 passes the ball out to O1, X1 closes out quickly to O1, pushing O1 toward sideline checkpoint while X2 closes out to a pass denial position against open O1. X5 rotates back to post O5, X4 rotates back to O4 as X3 stays with O3. Note: All rotations occur as ball leaves passer's hands. |
Phase 3. Final Match Ups Once matched up, all SOS fundamentals apply. When O2 passes the ball to wing O2, defender X2 assumes a SET position pushing O4 to corner or baseline checkpoint. Defender X5 FRONTS the low post O5 while X1 assumes a pass denial position against O1. X3 and X4 assume Helpside I positions against O3 and O4. |
